💬 Air Humidity Sensor - DHT

meanmrgreen

thats the irq pin in the radio post.
Not used by the radio

@flopp

thats the irq pin in the radio post.
Not used by the radio

I must have missed something or forgot. Is PIN 2 only used on Gateways?
Is it different between MyS version 1.x and 2.x?

hek

Tried to follow the history on the humidity file back in time on github.
At some point (2.0 release) the example was switched from HumiditySensor.ino (using pin 3) to DhtTemperatureAndHumiditySensor.ino (pin 2) created by @mozzbozz.

Not sure why the pin was switched, but you can run without the radio/IRQ-pin connection as long as not activating the MY_RX_MESSAGE_BUFFER_FEATURE.

flopp

@hek
All other examples are using PIN 3. Wouldn't it be easier to use PIN 3 for all examples? Maybe we shall wait and see if mozzbozz know why he changed to PIN 2.

hek

Ok, updated the example on github and instructions on the page back to pin 3.

Hello. Maybe someone could help hopefully..
I have arduino1 with 1 DHT22, which is over arduinoGW connected to RSPi with latest domoticz.
when i connect stuff up, after some time i see some strange childids, not related to this arduino1 in no way.
Lots of unknown!, with V_TEMP values, with V_HUM values, even V_FORECAST, V_PRESSURE and etc. which arduino1 should not send (or no other arduino on my area).

Illustration:
<img href="http://www.lstudio.lt/wp-content/uploads/dht22problem.png">
http://www.lstudio.lt/wp-content/uploads/dht22problem.png

my code is quite simple (for ex only temperature is shown)

#define CHILD_DESCR "TEMP3"
#undef CHILD_ID
#define CHILD_ID 31
present(CHILD_ID, S_TEMP, CHILD_DESCR);
delay(250) ;

loop:

  temp3=dht3.readTemperature();

if (temp3 >= 120) {temp3 = lasttemp3;}
if (temp3 <= -50) {temp3 = lasttemp3;}
MyMessage msg31(CHILD_ID,V_TEMP);
send(msg31.set(temp3,1));

so.. that is basically all

@Pavel-Larkin

I have also seen this, I noticed it last week. Some of my Nodes have those Unknown-child, but it is working correctly anyway.

Hello,
i have a problem with this sketch.
After downloading DTH.h froom Mysensors Examples, i have this error :
DhtTemperatureAndHumiditySensor:85: error: 'getConfig' was not declared in this scope

metric = getConfig().isMetric;

Any Idea of my mistake ?...

hek

It isn't your mistake, it's ours. The examples hasn't been updated correctly to reflect the most recent change in the api.

It should say getControllerConfig().isMetric

johnecy

I have the dht22 sensor hooked up and working on a pro mini on pin 3 I get a normal temp reading but the humidity always stays at 1.0 does not read.

Hello everybody,
hope, someone could help a newby
I've installed the MQTT - GW and would use the Air/Humidity - sensor. But it doesn't work properly.
The Connection to the Gateway seems to be okay. But I get no Air/Humidity - Information.
The sensor does not measure anything.
I've tried to change the data - pin, I've tried the DHT11 and DHT22 - sensor. No choice.
I'm getting mad

Thanks a lot.

gohan

Have you tried the basic arduino sketch that prints data to serial port?

donhuan78p

Hello,
thanks a lot for your answer.
Yes, I did. It produced the Messages as excepted.

gohan

So you'd better post your code so we can take a look at what is wrong with it.

donhuan78p

...sorry, Typo.
As expected

I am using dht22 outside. Does any one know how to change to whole number not decimal. The temperature outside change a lot. Let say temp 20.2 changed to 20.4 and still sends to getaway . If I do "send(msgTemp.set(temperature, 0));" and still receive both times 20 and 20, and I want only if change to 21 or 19.

mfalkvidd

@Arnold-Šlepetis change

float lastTemp;

to

signed int lastTemp;

and

float temperature = dht.getTemperature();

to

signed int temperature = dht.getTemperature() + 0.5; // Add 0.5 to get correct rounding

and

temperature = dht.toFahrenheit(temperature);

to

temperature = dht.toFahrenheit(temperature) + 0.5;

and

send(msgTemp.set(temperature, 1));

to

send(msgTemp.set(temperature));

You might also have to handle the isnan test.

Arnold Šlepetis

@mfalkvidd Thanks. It works like a charm

jwosnick

I've made a bit of an unusual observation in relationship to this script. I am running a fairly stripped-down version of it, but with the "standard" (not MySensors-customized) DHT library and its associated functions.

Here is the code:

// Enable debug prints
#define MY_DEBUG

// Enable and select radio type attached 
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69
//#define MY_RS485

#define MY_NODE_ID 47

#include <SPI.h>
#include <MySensors.h>  
#include <DHT.h>

// Set this to the pin you connected the DHT's data pin to
#define DHT_DATA_PIN 5

// Set this offset if the sensor has a permanent small offset to the real temperatures
#define SENSOR_TEMP_OFFSET 0

// Sleep time between sensor updates (in milliseconds)
// Must be >1000ms for DHT22 and >2000ms for DHT11
static const uint64_t UPDATE_INTERVAL = 10000;

#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1

bool metric = true;

MyMessage msgHum(CHILD_ID_HUM, V_HUM);
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
DHT dht(DHT_DATA_PIN, DHT22);
float temperature;
float humidity;

void presentation()  
{ 
  // Send the sketch version information to the gateway
  sendSketchInfo("TemperatureAndHumidity", "1.1");

  // Register all sensors to gw (they will be created as child devices)
  present(CHILD_ID_HUM, S_HUM);
  present(CHILD_ID_TEMP, S_TEMP);

  metric = getControllerConfig().isMetric;
}


void setup()
{
  delay(100);
}


void loop()      
{  
  
  // Get temperature from DHT library
  temperature = dht.readTemperature();
  if (isnan(temperature))
  {
    Serial.println("Failed reading temperature from DHT!");
  }
    
  else
  {
    send(msgTemp.set(temperature,0));
    #ifdef MY_DEBUG
    Serial.print("T: ");
    Serial.println(temperature);
    #endif
  }  

  // Get humidity from DHT library
  
  humidity = dht.readHumidity();
  if (isnan(humidity))
  {
    Serial.println("Failed reading humidity from DHT!");
  }
    
  else 
  {
    send(msgHum.set(humidity,1));
    #ifdef MY_DEBUG
    Serial.print("H: ");
    Serial.println(humidity);
    #endif
  }

  // Sleep for a while to save energy
  sleep(UPDATE_INTERVAL); 
}

I find that if I leave the last line as
sleep(UPDATE_INTERVAL);
then the sensor node ends up sending the same temperature and humidity values, over and over again, even if the actual humidity and temperature change.

However, if I change the last line to
delay(UPDATE_INTERVAL);
then everything works as expected.

This is with known good DHT22 units, so I suspect there is something funny about the sleep() function and the operation of the standard (not customized) DHT library.

It took a lot of poking around to discover this, but is this in fact the reason why the MySensors customized DHT library is required for this script? Is that library necessary to make sleep() and DHT temperature measurements play nicely together?

gohan

What libraries versions are you using?

mfalkvidd

@jwosnick the example sketch has this:

  // Force reading sensor, so it works also after sleep()
dht.readSensor(true);

which is missing in your sketch. The comment suggests that it might be relevant.

jwosnick

@mfalkvidd

Yes, absolutely. But it appears that the dht.readSensor() function is not actually part of the standard DHT library, but rather something that only appears in the MySensors-customized version of it. I'm trying to get a handle on why there is a need for a customized library.

mfalkvidd

@jwosnick seems like the most recent version of the original library calls readSensor when getTemperature is called.

Maybe the most recent version can be used if the MySensors example sketch is rewritten to just use getTemperature? Would it be possible for you to test this? It would be great if we could get rid of the MySensors-custimized version of the library and just let people install the standard DHT library.

jwosnick

@mfalkvidd said in Air Humidity Sensor:

@jwosnick seems like the most recent version of the original library calls readSensor when getTemperature is called.

Yes, it does... but somehow that function is not "exposed" to the outside world. With a standard DHT test sketch (nothing to do with MySensors) calling readSensor throws an error.

mfalkvidd

@jwosnick yes. But since readSensor is called inside getTemperature, there should be no need to call it manually.

avgays

@jwosnick

As your set sensor model

DHT dht(DHT_DATA_PIN, DHT22);

it looks like you use "Adafruit DHT-sensor-library".
It's need dht.begin(); in setup(){ } which is missing in your sketch

jwosnick

@avgays
Good catch -- thanks. Yes, that is the library I am using.

Despite omitting that line, the script above works fine as long as the last line is a delay() function and not sleep(). If I use sleep(), it in fact appears to work, but sends the same temperature and humidity over and over again. So it is something about the sleep() function.

I will add in the dht.begin() and then put sleep() back in and see what happens.

jwosnick

@avgays Confirmed that even with dht.begin(); the script still sends the same temp and humidity info, over and over again, as long as the sleep() function is in there. As soon as sleep() is replaced by delay() it all works properly.

So I conclude from this that the MySensors-customized version of the DHT library must have something in it to make sleep() play nicely with the DHT unit. I wish I knew what that was. It would be ideal if this sensor (and the Dallas Semiconductor one) could be used with the MySensors system with their standard libraries.

avgays

@jwosnick
Very strange as in my case this library work well with sleep() on battery-powered node.

Look like it's nessesary to add delay(2000); before or after sleep() as sleep mode stops all timers, so
currenttime - _lastreadtime =0
and function returns with no new measurements.

Digdogger

Hi,
I would like to use this example and reduce power consumtion by removing the regulator on the mini Pro and the power led.
If we remove the regulator, we can power the board with 3V on Vcc. It will be OK for the mini pro and the NRF but the DHT22 needs 3.3V minimum. The solution will consist to use a step up boost module. What is the current consumtion of the step up boost?

gohan

I don't know about DHT22, but NRF24 can work down to 1.8 or 1.9V so you can connect it directly to battery (take a look ad EasyPCB)

AWI

@Digdogger it's better to get rid of the DHT and use something more reliable and operating at lower voltages. Like si7021, sht21 or Bme280

Digdogger

Thanx for your answers. @AWI, the BME280 looks great and not expansive i will replace the DHT by this one. Thank you.

jwosnick

@Digdogger
Out of curiosity, do you expect there to be a big savings in power consumption by removing the regulator and power LED? I've never used the Mini Pro (the smallest I get to is the Nano) but I understand it already is very efficient with power usage.

Digdogger

@jwosnick: please take a look here: http://www.home-automation-community.com/arduino-low-power-how-to-run-atmega328p-for-a-year-on-coin-cell-battery/.
You'll see that the current saving is significant (almost 40% saving)

gohan

@jwosnick
Arduino is efficient for a live node, but for a battery powered sleeping node voltage regulators have a small drain on battery; led also consumes some power. The Nano has also the usb chip that is powered but not used that also increases battery drain. So, as rule of thumb, everything that is not really used/necessary will drain some battery over time.

mfalkvidd

@jwosnick with the led and regulator, battery life on 2xAA is about three weeks. Removing them will usually give you 2-5 years.

jwosnick

@mfalkvidd

Thank you. I didn't realize the differences were so stark.

I have some Pro Mini 3.3V units on order and hope to convert my sensors to that platform, when they arrive.

hashem25

hello I ran it but i didnt see anthing except the garbage in com monitor

@hashem25 said in Air Humidity Sensor:

hello I ran it but i didnt see anthing except the garbage in com monitor

Hello, you need to change the baud rate at the bottom right of the Arduino serial monitor window until you see clear text.

hashem25

thanks it works

anno

How do i get 2 dht22's working in the code?

gohan

If you already have one, it is a matter of just repeating your code for the first sensor and just change the pin number where you connected the second one

ianatkin

This example doesn't seem to be included in the latest library version - am I being blind or is this deliberate?

mfalkvidd

@ianatkin that is correct. Follow the instructions under the "Example" headline on the build page.

ianatkin

@mfalkvidd Thanks

mfalkvidd

@ianatkin you're welcome. Great to see a new forum member

godwinguru

Is it the same code that i will burn to the controller circuit. Can someone help me with a little explanation on the code for the controller circuit so as to be receiving the temperature values

MrVince

Hi ! Thank's for working
I add the libraries in "MySensors external examples" to Arduino IDE but when I want to compile I have this one log error :

DhtTemperatureAndHumiditySensor.ino:43:25: fatal error: MySensors.h: No such file or directory
compilation terminated.

In MySensors folder's libraries, I have a MySensor.h, without 's' . This is one? Do I forget something?

Thanks

mfalkvidd

@MrVince sounds like MySensors 1.x is installed. Remove the MySensors folder and install the latest version. Instructions: https://www.mysensors.org/about/arduino#installing-the-sensor-libraries

godwinguru

Please can someone help me on how I can be able to access the temperature and humidity data sent by the sensor on the gateway. I am recently working on sending temperature and humidity data to a controller. I used the above .ino code( /mysensors/MySensorsArduinoExamples/examples/DhtTemperatureAndHumiditySensor/DhtTemperatureAndHumiditySensor.ino) as it is and ensured my data pin is pin3 and for my gateway am using this(/mysensors/MySensors/examples/GatewayW5100/GatewayW5100.ino). I did not make any changes on both codes as i am new and do not have knowledge of what to do. I was receiving the following on the sensor serial monitor

Please can someone tell me what to do and how I can access the sent temperature and humidity value at the gateway. If there is further code to add to the one I have referenced, please do let me know.
Thanks

@godwinguru - your radio on the gw isnt initialised.
Check wiring and power.

Is it now ok, how can i get my data at the gatewa?

sundberg84

@godwinguru - I dont know why but it seems like your gw is restarting. I dont know anything about a Raspberry GW so you need to wait for someone else to answer.

Top of my mind is a power issue.

Also I added ``` around your code which makes it easier for others to read. Please use this when you post logs.

godwinguru

@sundberg84, thank you for your reply, my gateway is Ethernet with arduino, am not using rhaspberry pi., thanks once again.

sundberg84

@godwinguru - then I would say you have a power issue. As something is using power the gw restarts due to this. What controller do you use? Do you see any connection status there? How do you power the gw? This is crucial that you use a capacitor on the radio and have a stable power supply för the radio.

godwinguru

@sundberg84, as i said, am new to mysensors, i dont know where and how to select a controller, it is in my mind to use homegenie, but i still dont know how to integrate it with the gateway, am using adapter to power it, it may not be power problem, i think i still to know a lot about how mysensors works. This is because i used this code (/mysensors/MySensors/examples/GatewayW5100/GatewayW5100.ino) on the gateway without changing anything. i doubt if that is okay, because i never added any other thing to the code.

sundberg84

@godwinguru - ok, then thats your problem. The GW cant be used on its own - it require a controller to work. The controller hand out ID and collect all the data. The controller can be used on a raspberry pi for example.

Digdogger

Hello,
problem, after each restart of gateway or restore database, all my temp/humity sensors are seen as 2 sensors.
Seen like that:
2017-07-15 15:23:53.758 (Mysensor) Temp (Temp)
2017-07-15 15:23:53.763 (Mysensor) Humidity (Hum)
Should be (on another sensor):
2017-07-15 15:26:45.610 (Mysensor) Temp + Humidity (Salon)

After 3 hours one sensor is still doing the same. I restarted it, no change.
Restarted the gateway again, no change. There is still one sensor which has this behaviour and it's never the same sensor...

gohan

It's a Domoticz problem, sometimes just rebooting everything can solve but try to search on domoticz forum too.

cristi

2 issues I see with the example:
a) I'm not a native english speaker, but to me, on top of the page, "sampling rate" of "2 times/sec" for dht-22 is wrong. From code and pdf you can see that you can't ask for data faster than at 2 seconds.
As such, I would change the top of the page to read either "0.5 times/sec" or "1 time at 2 seconds".

b) use of SENSOR_TEMP_OFFSET is wrong. Because depending on how the controller wants this sensor's data (Celsius | Fahrenheit), the offset will be different. If you happen to change the metric system value in the controller and ask for the data (after sensor restart let's say), you'll get a different value than expected).
I would do:

- add to the comment for SENSOR_TEMP_OFFSET that we're talking about a Celsius offset
- and move the statement "temperature += SENSOR_TEMP_OFFSET;" before the conversion to Fahrenheit.

Regards.

mfalkvidd

Thanks @cristi
I have updated the table with the sample rate. Could you check if it looks good?

For the code change a pull request will be needed. Could you do one? If you can't I'll add it to my todo but it might take a while.

cristi

@mfalkvidd

there's a typo in the table for DHT-11: it should be '1s per sample' instead of '10s per sample'
I created a pull request

mfalkvidd

@cristi according to http://www.micropik.com/PDF/dht11.pdf typical response time is 10s. Am I looking at the wrong number?

Great work on the pull request. I'm adding a link in case someone needs it in the future. https://github.com/mysensors/MySensorsArduinoExamples/pull/29/

cristi

@mfalkvidd Indeed, I see that 10 seconds in pdf, but it looks strange. I'd have to re-read to see if I can get what it is supposed to be for.
But, meanwhile, in the same pdf, you get this note (chapter 6): "Note: Sampling period at intervals should be no less than 1 second.". Also, DHT library is using 1second sampling period.

mfalkvidd

@cristi thanks. I have updated the table.

ricmail85

I've created a DHT11 sensor based on this sketch. However the temperatures (and humidities) are reported as integer numbers in domoticz (either by looking at the devices and setup tabs). In the sketch I've specified the number of decimals like send(msgHum.set(temperatire, 2)). Even if I try larger decimal numbers, nothing change when the value is received in domoticz. What can I do?
Thanks in advance.

gohan

What kind of variable did you set for your "temperature"? If you can post your code it would help

mfalkvidd

@ricmail85 you mean you're only getting integers here?
0_1516118501351_97c9afbc-5d93-4fc1-8886-2d8e6fd7c22c-image.png

ricmail85

@mfalkvidd yes I see only integer numbers here and in devices.

@gohan I've declared the variable temperature as float. However after I bit of debugging I found that it seems to be related to the dht lib included in the mysensors examples. If the model is dht11 the library is set for 0 decimals. For the dht22 it would be 1 decimal.

Am I right? Thanks in advance

The is the log parser on the mysensors site. Anyway that means you didn't set a node ID on your node and it is asking for one but there is no controller providing one.

@gohan Thank you I was able to resolve that issue and get it communication with the gateway, the vera and now mqtt. Thanks again!

joaoabs

For the ones looking for a library that makes this DHT sketch work, mysensors have compiled a set of libraries that include this DHT.h and many others. Just go to https://www.mysensors.org/about/arduino#optional---install-external-mysensors-examples (yes, the name is not intuitive, maybe the keyword library would make it more obvious?), or jump directly to here and follow the standard library instructions. It took me two hours to find this, hope it saves time for future followers of mysensors like myself.

Good luck!

joaoabs

Here is the set of libraries where you can find the DHT.h: https://github.com/mysensors/MySensorsArduinoExamples/archive/master.zip

Pavel Polititsky

If I use this string in a code "sleep(dht.getMinimumSamplingPeriod());" DHT22 (AM2320) always read NaN
else DHT22 working, but never sleeping
What im doing wrong?

joaoabs

Where are you reading this "NaN"?
I sometimes also have it in my OpenHab controller webpage when the node doesn't communicate for a while... But when it does, it changes to the value it read from the sensor.

Try to see in the GW if there is traffic comming from that node. Usualy you can read there the values.

Good luck!

Pavel Polititsky

In a serial debug of the sensor module
It write something like "Failed to read data humidity (temperature)
Also no send any data to gateway

Without getMinimumSamplingPeriod I've receiving hum & temp through gateway

gohan

DHT sensor is not very fast, it needs some times between initialization and the different readings

Maschler

Hi
this program doesn’t work with my setup. For the Gateway I am using a Ardunio nano as a serial Gateway. Thus, I am using the GatewaySerial.ino. Even the Node is based on an Arduino nano with a DHT22 connected. The general communication between both seems to work. But I do not receive any sensor data. When testing the setup with another library for the dht sensor, it works fine (without sending to the gateway, only serial Monitor). Because I am new in the mysensors community there is perhaps a simple mistake which I don’t see… I hope you can help me finding my mistake.
Here is a short extract of the Debugging Information’s. As far as I see there are no data transferred.

Hi!
What controller are you using?
From the logs it seems that the sensor is asking for an ID but does not get any.
Node ID is handed out by the controller. Or else you have to set the node ID in the sketch. What does the sketch look like?

Maschler

Hi
thanks for reply. I am using this sketch: https://github.com/mysensors/MySensors/blob/development/examples/GatewaySerial/GatewaySerial.ino
The only thing I changed is the radio type and I disabled the inclusion mode.

Yes but the issue is with the sensor node. What sketch are you using there?

Maschler

Oh. I am using the sketch in from above and only changed the radio module.

@bgunnarb
You are right. I had to define a sensor id and now it works perfectly Thank you very much!

Note: Double check your DHT11 module! The pinouts of the PCB of my DHT11 module differed from those in this article. My leftmost pin was Data out, the middle pin was VCC and the right was GND.

Hi all,
I recoded this sketch and I posted on GitHub (1 year ago, and I updated it today). It runs good from 1 year with no issues.
I don't know why it's still not merged in master branch. I forgot to do some action??
Can anyone help me? please.
Meanwhile you can download and use it; this is its link:
https://github.com/cnerone/MySensorsArduinoExamples/blob/master/examples/DhtTemperatureAndHumiditySensor/DhtTemperatureAndHumiditySensor.ino

@cnerone no you did 't forget anything. It is just that the external examples don't get much attention and are a bit truoublesome (due to the need of handling third party libraries).

I used the code that cnerone has in his comment below with a nano and DHT22 and it worked great. For my nano I did have to use the 'old' bootloader for the program to download into the nano correctly with the arduino IDE. The code in the example here wouldn't compile for me, I think because someone changed the DHT library but for some reason kept the name the same so I ran into some kind of conflicts with variables. I wish when people modified libraries they would give them new/different names because the IDE does not have a good way of handling multiple libraries with the same name. BTW: That is not a MySensors issue, it's the IDE.

Also, I could not get a clean compile/download to a arduino mini 3.3v with 168 processor. From what I could find there is not enough memory to handle the newest mysensor libraries, at least that's what some people are saying in forums. I didn't spend much time on it and moved on to other arduinos.

For any one that needs it this is how I got the DHT22 to work.
This is my poor attempt at trying to get the DHT22 to work as the original code
https://github.com/cnerone/MySensorsArduinoExamples/blob/master/examples/DhtTemperatureAndHumiditySensor/DhtTemperatureAndHumiditySensor.ino
will not compile for me.
