Multisensor PIR problem [solved]
-
#define PIR_SENSOR_DIGITAL 3 // The digital input you attached your motion sensor. (Only 2 and 3 generates interrupt!) #define INTERRUPT PIR_SENSOR_DIGITAL-2 // Usually the interrupt = pin -2 (on uno/nano anyway) #define HUMIDITY_SENSOR_DIGITAL_PIN 2 #define LIGHT_SENSOR_ANALOG_PIN 0Are you connecting both DHT and PIR at same pin 2 ? That must be the cause (DHT is triggering the interruption, I think you want only the PIR to trigger it).
Edit: looks like your PIR is at pin 3 , and DHT on pin 2 --- Should be the inverse? The PIR should be on pin 2 (to trigger the interrupt).
@rvendrame Pir sensor is defined as 3
interrupt pin is defined as INT1: 3 - 2 = 1
-
So PIR must connect on PIN 1 and not PIN 3.
Edit: Better, how did you connect DHT and PIR?

@rvendrame The DHT is on pin 2 and the pir on pin 3. i use the MYS PCB.
i suspect the delay function disturb the sleep function. if i dont use the delay, the dht cant "heat up".
far as I know the interrupt is only an internal value. right?

Yes, it looks fine. What exactly error are you having? From your first serial monitor, it looks like your sensor woke on every 10min aprox, ( 6608 / 11148 / 15441 ).

-
So PIR must connect on PIN 1 and not PIN 3.
Edit: Better, how did you connect DHT and PIR?
@rvendrame When the PIR is connected to PIN3 the interrupt is INT1. Pin 1 does not have an interrupt.
Only pin 2 and pin 3 have an interrupt.
Pin 2 = int0
pin 3 = int1
-
if you put the delay() inside that 'if ( mills() > mytime ) ' , what happens?

This can't work well. Your interrupt is set on pin1 - 2 = int-1?
What happens when you remove the pir and use a switch instead?
-
@n3ro , what is wrong at your last test? The PIR is reporting 0 and 1, and from time to time there is a temp/hum report as well.
@rvendrame in my last test the pir sends endless 0 and dont sleep
-
Which arduino PIN do you use to connect the PIR?
-
Perfect. If it is working fine with a switch --- Maybe your PIN is triggering false positives? Or maybe the PIR output is floating a bit, and arduino is triggering it more than it should?
-
If a switch works than the only could be the pir itself. You have enabled the pull-up resistor so an open collector should not give floats.
You already told that a sketch with a pir only worked fine?
Well, i can test what happens with my dht22 and a pir tomorrow (with your sketch).
