Motion Sensor stopped working on combined sketch ( Hum, Temp, Motion + Bat Level )



  • Hello:

    **Please see edit BELOW:

    It appears that after a while the motion sensor actually works.... It's something to do with the sleep time....

    What I am trying to do is have the sensor sleep as much as possible to save battery, BUT should always trigger on motion movement. I think I have an error with sleep values and that is affecting the motion sensor from triggering.

    If anyone could recommend a way to sleep the unit as much as possible ( 3 in 1 Temp, Hum, Motion, + Bat reporting ), but always trigger when motion is around that would be greatly appreciated.**

    Sorry if this is a bit of a newbie question, but I can't figure out why my motion sensor stopped working in my sketch? It works fine if I upload the basic mysensors motion sensor sketch, but as it is combined in this code, it no longer reports any motion movement back ( physically waving my hand in front of it has no reaction ). I have tried to combine the following code, and also trying to make it as ultra lower power as possible, as it will be a small battery operated ( 3 x AA Batts ) pro mini, 8Mhz, 3.3v . Can anyone please suggest what I have done wrong? Below is the code:

    If I upload an older sketch, or even the basic motion sensor sketch, no issues, so it's not a hardware issue, just the combination of sketches broke the motion sensor readings ( 0 or 1 )

    Thanks very much

    You don't activate the interrupt while sleeping. Look at the basic motion example, where the sleep method is called.



  • Yeah, @TimO Is right.

    Check the code example here http://www.mysensors.org/build/motion and look for the gw.sleep sentence.

    I have a similar sensor and this is what I have in my scketch:

    gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME);

    The problem with your sentenc is that the sleep command is not overridden by the motion detection. You need to include the interruption as part of the sleep command.
