    if i use this

      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?

        @Sweebee
        is #define INTERRUPT PIR_SENSOR_DIGITAL-2 wrong?

        when i use a switch it looks OK

          @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.

              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).

                        @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

                        I also made a few more notes in the code:

                        #include <MySensor.h>
                        //#include <readVcc.h> // cannot see where you are using this library yet
                        #include <SPI.h>
                        #include <DHT.h>
                        
                        #define NODE_ID 10                       // ID of node
                        unsigned long SLEEP_TIME = 10000UL;        // Sleep time between reports (in milliseconds)
                        
                        #define CHILD_ID_PIR 1                   // Id of the sensor PIR
                        #define CHILD_ID_HUM 2                   // Id of the sensor HUM
                        #define CHILD_ID_TEMP 3                  // Id of the sensor TEMP
                        #define CHILD_ID_LIGHT 4                 // Id of the sensor LIGHT

                          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

                          I also made a few more notes in the code:

                          #include <MySensor.h>
                          //#include <readVcc.h> // cannot see where you are using this library yet
                          #include <SPI.h>
                          #include <DHT.h>
                          
                          #define NODE_ID 10                       // ID of node
                          unsigned long SLEEP_TIME = 10000UL;        // Sleep time between reports (in milliseconds)
                          
                          #define CHILD_ID_PIR 1                   // Id of the sensor PIR
                          #define CHILD_ID_HUM 2                   // Id of the sensor HUM

                          Hey, its a good idea to send only PIR if changed!
                          The unused code in the sketch is because i have reduced the used functions to the minimum to debug it better. The full sketch has LDR and battery lifetime output too.

                          i have added some extra output in the modified sketch:

                          #include <MySensor.h>

                          #define CHILD_ID_PIR 1                   // Id of the sensor PIR

                            i think millis didnt work with sleep. the counter is not increasing when sleeping..

                              @n3ro said:

                              delay(dht.getMinimumSamplingPeriod());

                              you dont need this:

                              delay(dht.getMinimumSamplingPeriod());
                              

                              since you are sleeping longer than the minimum sampling period

                              try like this, removing the timer, just use the sleep period t update temp/humidity (untested):

                                @n3ro said:

                                delay(dht.getMinimumSamplingPeriod());

                                you dont need this:

                                delay(dht.getMinimumSamplingPeriod());
                                

                                since you are sleeping longer than the minimum sampling period

                                try like this, removing the timer, just use the sleep period t update temp/humidity (untested):

                                when i use this sketch the PIR works but the DHT cant read:

                                Failed reading temperature from DHT
                                Failed reading humidity from DHT

                                    @BulldogLowell the wires are OK.

                                    In sleep the DHT cant warm-up. so the dht need 2 sec before read. when i dont use the delay i cant read it.

                                    i dont understand why the interrupt didnt work with the enabled delay.

                                    do you have tested on a arduino?

                                        @n3ro, i'm glad you fixed it. DHT was on PIN3 before, right? Pin 2 & Pin3 are connected to the interrupts, maybe this was the problem.
