Multisensor PIR problem [solved]

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 ...

i have posted it before this post:

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?

n3ro

@n3ro said:

#define PIR_SENSOR_DIGITAL 3

:)

rvendrame

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?

Sweebee

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).

n3ro

@Sweebee thy this would be very nice :)

You find my sketch here:
https://github.com/n3roGit/MySensors_n3ro/tree/master/MotionSensor_DHT_light_battery_mod

BulldogLowell

@n3ro

you are sending an update on the PIR status every time the arduino wakes from a sleep, which you don't need.

Also, and this probably isn't a problem right now, but will case a problem later, use unsigned subtraction in your millis( ) timers

could not see where you were using the library, so I commented it out below, not having it on my computer
