Multisensor PIR problem [solved]

rvendrame

What is this number? Did you print the milis()?

send: 10-10-0-0 s=1,c=1,t=16,pt=0,l=1,st=fail:0
6608 <<<<<<

n3ro

Serial.println(mytime);

yes :)
Serial.println(mytime);

rvendrame

#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 0

Are 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).

Sweebee

@rvendrame Pir sensor is defined as 3

interrupt pin is defined as INT1: 3 - 2 = 1

rvendrame

So PIR must connect on PIN 1 and not PIN 3.

Edit: Better, how did you connect DHT and PIR?

n3ro

@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?

rvendrame

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 ).

The DHT gives only output the first start and the pir interrupt works perfect.

When delay(dht.getMinimumSamplingPeriod()); is activated the DHT works and the pit interrupts the whole time :(
In this configuration the arduino never sleeps ..

EDIT: i have changed the sleeptime for testing to a shorter time

Sweebee

@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

rvendrame

if you put the delay() inside that 'if ( mills() > mytime ) ' , what happens?

n3ro

@Sweebee is it possible to fix the problem when DHT is connected to pin 4?

rvendrame

@n3ro said:

It worth a try ...

Sweebee

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

@Sweebee
is #define INTERRUPT PIR_SENSOR_DIGITAL-2 wrong?

when i use a switch it looks OK

rvendrame

@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.

n3ro

@rvendrame in my last test the pir sends endless 0 and dont sleep

rvendrame

Which arduino PIN do you use to connect the PIR?
