    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)

    @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

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

    @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.

    @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)

    @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.

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

    @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.

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

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

    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

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

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

    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

    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

    @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

    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

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

    @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.

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

    @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.

    @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.

    @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.

    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...

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

    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.

    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.

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

    @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/

    @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.

    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.

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

    @ricmail85 you mean you're only getting integers here?

    @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.

    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!

    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?

    0
  • 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!

    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

    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?

    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.

    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:

    @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.

  • rmalbers

    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.

    @catchra This bit might be important.....
    "This example uses a modified version of the external DHT library, which is included in the MySensors external examples. Please install it and restart the Arduino IDE before trying to compile."

    Did you do this already?

    ya i did try that 1st but it did not work so I tried to get it to work with the updated lib and so far it has been working well
