3-in-1 Humidity Temp and Motion

[Anthony Straw]

@Konrad-Walsh my nano and pro mini on the way! double each! cant wait!! fed up all confused so have ard r3 n mega n nano n promini all tick tick!

[djolafritte]

Works like a charm...

Thanks for sharing :)

[Dylano]

dear all.
What battery u use?
And what is the battery time?

[viableoption]

Looks pretty sweet. How is it working comparing to existing products with the same features?

[Łukasz Kostrzewa]

Hi Konrad

Thx for great code. It works like charm but...

I have a question... It is possible to add to Your code one more (Door/Window) sensor?

Mayby You can post that code on this forum?
Best regards

[Łukasz Kostrzewa]

Hi to all

I changed a little Konrad sketch and add to 3in1 Humidity Temp and Motion one more sensor (Door\Window)

Here is my code:

#include <SPI.h>
#include <MySensor.h>
#include <DHT.h>
#include <Bounce2.h>

#define CHILD_ID_DOOR 3
#define BUTTON_PIN_DOOR 2
#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
#define CHILD_ID_MOT 2 // Id of the sensor child
#define HUMIDITY_SENSOR_DIGITAL_PIN 4

#define DIGITAL_INPUT_SENSOR 3 // The digital input you attached your motion sensor. (Only 2 and 3 generates interrupt!)
#define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)

unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)

MySensor gw;
Bounce debouncer = Bounce();
int oldValue=-1;

DHT dht;
float lastTemp;
float lastHum;
boolean metric = true;
MyMessage msgHum(CHILD_ID_HUM, V_HUM);
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
MyMessage msgMot(CHILD_ID_MOT, V_TRIPPED);
MyMessage msgDoor(CHILD_ID_DOOR,V_TRIPPED);

void setup()
{
gw.begin();
dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN);

pinMode(BUTTON_PIN_DOOR,INPUT);
digitalWrite(BUTTON_PIN_DOOR,HIGH);

debouncer.attach(BUTTON_PIN_DOOR);
debouncer.interval(5);

// Send the Sketch Version Information to the Gateway
gw.sendSketchInfo("4in1", "1.0");

pinMode(DIGITAL_INPUT_SENSOR, INPUT); // sets the motion sensor digital pin as input

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

metric = gw.getConfig().isMetric;
}

void loop()

{
// Read digital motion value
boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == HIGH;

Serial.println(tripped);
gw.send(msgMot.set(tripped?"1":"0")); // Send tripped value to gw

delay(dht.getMinimumSamplingPeriod());

float temperature = dht.getTemperature();
if (isnan(temperature)) {
Serial.println("Failed reading temperature from DHT");
} else if (temperature != lastTemp) {
lastTemp = temperature;
if (!metric) {
temperature = dht.toFahrenheit(temperature);
}
gw.send(msgTemp.set(temperature, 1));
Serial.print("T: ");
Serial.println(temperature);
}

float humidity = dht.getHumidity();
if (isnan(humidity)) {
Serial.println("Failed reading humidity from DHT");
} else if (humidity != lastHum) {
lastHum = humidity;
gw.send(msgHum.set(humidity, 1));
Serial.print("H: ");
Serial.println(humidity);
}

debouncer.update();
// Get the update value
int value = debouncer.read();

if (value != oldValue) {
// Send in the new value
gw.send(msgDoor.set(value==HIGH ? 1 : 0));
oldValue = value;
}

// Sleep until interrupt comes in on motion sensor. Send update every two minute.
//gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME);
}

Now it is 4in1 :)

Has the 3in1 sketch been updated to 2.0 yet? I need some help with it, im not tot keen with coding...

[r-nox]

@kurniawan77

This is HUM TEMP and PIR

This is what I'm using and it runs in mysensors 2.0

None battery powered. NO sleep mode and dirty code but it runs well enough for me right now.

[ikkeT]

My sample is here, unfortunately I didn't see this thread before starting it :)
It works for temp, humidity, door and motion, and interrupts for door and motion, otherwise sleeps the intervals:

https://github.com/ikke-t/sensebender

There is also pro-mini to code to monitor only door and motion.

This is also for 2.0 MySensors.

I combined Motion and Air Humidity and Sleep works. This is my first one and I'm pretty sure I have some unnecessary code in it.

I did some work today getting this temp / humidity / motion combo sensor running. The main issue I ran into was that though the temp and humidity did not report their values to the GW unless there was a change in values or the max no update trigger was reached, the motion sensor would report it's state value each cycle. @McPostal you also should be seeing this in your code. While this is not an issue if you are powering with a AC adaptor, I am planning on using batteries down the road for these sensors so I do not want it to broadcast unless required.

I added some code to resolve this. I am still testing this out but in theory this code should allows the Motion sensor to sleep and only report on a state change or when the max no update trigger is reached.

Nice! I realized the motion was being updated every cycle after I posted my code. I also left out references to metric temperature readings. I fixed the motion part in my code but didn't post it yet because I had already added a second motion sensor. What I did different was not forcing the motion update. I want the time stamp to reflect the last time someone was in the room.

However, when i look in domoticz the relay isnt presented as a child.
Plus, the motion sensor is called "S_LIGHT_LEVEL" and not "S_MOTION" as it does in my other device (that only have temp, hum motion and not a relay in the sketch).
temp/hum sensor and motion sensor works as intended in domoticz.
My first though is that the motion and relay somehow is a bit mixed up by the sketch, but im kinda new to this so im not sure.
Would really appreciate if someone can look at the sketch and see if there is any obvious problem :)

@stocken

Under "void presentation()" , present(CHILD_ID_MOT, V_TRIPPED); //me should be

present(CHILD_ID_MOT, S_MOTION); //me

that should fix the light level problem.

I haven't done a relay yet. If no one else responds I look at it later tonight. I also have a relay but haven't had time to try and implement it yet.

Hello everybody,

first off all a big thank you for creating this awsome sketch. It works perfect for me !!
But, as you might already have guessed I have a little problem.

I built 2 exact same nodes and flashed the exact same sketch ( only thing I changed is the child ID´s) but one node works just like a charm ( MSPIRAndy) but the other one (MYSENSOR_106) doesnt transmit its readings (?)

Via the serial monitor the readings do exist and work perfect.

Thanks a lot, all help is appreciated

Have you tried swapping radio between the 2 sensors? Just to exclude any radio issue

[Komaandy]

Yes i did swap the radios, but what seems to be the problem is the arduino itself.
When swapping the arduinos ( both arduino pro mini 3,3 volt) both flashed with the same sketch one works and the other just doesnt.
I just swapped the arduinos on the breadboard and left everything else in place...
Thats really strange, given the fact that BOTH transmit good readings when connected to the arduino-serial-monitor ...

Do you have a schematic that you could post?

@ryanbrown204 welcome to the MySensors community!

This is a long thread with a lot of different people posting, so it is a bit hard to guess which schematic you are looking for. Could you clarify?
