Multisensor PIR problem [solved]

n3ro

dht.begin();

Hey torfinn,

i get this error when compiling:
MotionSensor_DHT_light_battery_mod.ino: In function 'void loop()':
MotionSensor_DHT_light_battery_mod.ino:109:7: error: 'class DHT' has no member named 'begin'
Fehler beim Kompilieren.

n3ro

I have a idea,

is it possible to build a second loop like this?
But now i have one problem... the loop2 never run...

i have downloaded THIS

But i get this error when compiling:

rvendrame

@n3ro , you can have only one loop().

You need to merge the two logics into into a single loop. You might also want to remove the second sleep, otherwise PIR will not trigger there.

n3ro

@rvendrame do you have an idea how to do it?

rvendrame

Maybe you can start by to removing these 3 lines:

}
void loop2()
{

... and move the 1st sleep to the end of loop (where the 2nd sleep is):

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

.... and remove the 2nd sleep:

gw.sleep(SLEEP_TIME);

the pir works fine. but the dht doesn't work.

when delay(dht.getMinimumSamplingPeriod()); is used the dht works and the pir fails.

rvendrame

It makes sense ;-) Try this:

create (outside the loop) a variable to count the time:

long mytime = 0;

.. and replace the delay by :

 if ( milis() > mytime )  { 

   <  Put the dht stuff here > 

  mytime = millis() + dht.getMinimumSamplingPeriod() ; 

}

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

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 ).

i get this output after starting:

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?

It worth a try ...
