Converting to 2.0 Slim Node as a Mini 2AA Battery PIR Motion Sensor code



  • Hello,

    I'm trying to convert @m26872 Slim Node as a Mini 2AA Battery PIR Motion Sensor code, from 1.5 to 2.0 MySensors library, but becose I'm very begginer at programming I facing with some unknow issues for me.

    Converted code from 1.5 to 2.0 MySensors library:

    /**
     * EgSlimReed2
     * Sketch for Slim Node and HC-SR505 based motion sensor. 
     * Inspired by:
     * - MySensors motion sensor example: http://www.mysensors.org/build/motion
     * - AWI's CR123A based Slim Node motion sensor: http://forum.mysensors.org/topic/2478/slim-cr123a-2aa-battery-node

     *******************************
     *
     * REVISION HISTORY
     * Version 1.0 - Test to if node can operate in some way dealing with the Pir extreme sensitivity to noise on Vcc.
     * Version 2.0 - First "production node". "Inactivity day counter" introduced.
     * 
     * DESCRIPTION
     * This sketch will only send trips as "1" to the controller. It's up to the controller to deal with the info. 
     * The motion node will not notify controller when resets back to low state and is ready for a new trip. In reality 
     * this is ~10s. And EVEN IF motion is detected continuously, there will be no new trip until motion has stopped for ~10s.  
     * The HC-SR505 is very noise sensitive and will trigger spuriously for almost any activity 
     * on Vcc (test thoroughly). To run the HC-505 at low voltages (tested flawlessly down to 1.6V), 
     * the 7133-reg and diode are removed (and possibly increase the sensitivity even further). 
     * Solution is to deal with it by interrupt type, check which source, block by sleep time etc.
     * 
     * HC-505 output connects to MOTION_INPUT_PIN (here D3) without any supporting component. Input pull-up disabled.
     * Every 24 hrs without trip, increments a counter and after "BATTERY_REPORT_DAY" counts a battery report will be sent as a heartbeat signal.
     * Else a battery report will be sent after every "BATTERY_REPORT_BY_IRT_CYCLE" motion trips.

    When I compiling code on arduino I get:

    Warning: Board arduino:avr:apm96 doesn't define a 'build.board' preference. Auto-set to: AVR_APM96
    In file included from C:\Users\Moni\Documents\Arduino\sketch_aug11c\sketch_aug11c.ino:37:0:

    exit status 1

    I was trying to reinstall MySensors library, but it didn't help.

    Maybe someone could advise, where I made a mistake in code when converting it?

    Thank You!

    @jacikaas I'm not very up-to-date on anything in these days :disappointed: , but it looks like a preference is missing from the "boards.txt" in Arduino IDE. Which IDE version do ou use? Can you post the "boards.txt" please?



  • @m26872
    Actually that one error with preference:

    Warning: Board arduino:avr:apm96 doesn't define a 'build.board' preference. Auto-set to: AVR_APM96
    

    ...was also on 1.5 library and sketches was succsessfully uploaded.

    Which IDE version do ou use?

    I'm using 1.6.10 Arduino IDE version.

    Can you post the "boards.txt" please?

    Yes, of course. In boards.txt file I paste same configuration description as in this link, at the end of file:

    Do I need to post whole boards.txt file?

    @jacikaas Ah! Forget about the warning. You error comes from that you haven't put your MySensors-related defines before the "include MySensors.h". Look here link.



  • @m26872

    A golden rule - RTFM. Next time I will use it :)))

    Thank You, that was it! Now code is compiling. But I think my HC-SR505 is broken, becose it don't see any movement.

    I need to order new one :)

    A lot of thanks!

    @jacikaas said:

    But I think my HC-SR505 is broken, becose it don't see any movement.

    Did you test it with just a simple LED+resistor at the output ? Another option is to just measure the supply current (47uA when idle, 64uA for 10s after trigger).



  • @m26872

    Yes, now I test it with LED+resistor. It's definately broken, becose if I hide PIR sensor, data output always get high. LED light up for a while, then goes down for 2-3s and goes up again. And it repeating all the time, when it is covered (no movement in background).

    Thanks for Your help @m26872 !



  • Tried this setup and its not working very well for me, can be a busted PIR but I don't know.
    It seems like it sometimes work, but if I leave the room and then enter it can take long time until the PIR triggers.

    If i put a LED and a resistor I do that between GND and signal or where do I place it?





  • Thanks I'll try that
