Motion Sensor Stop Working after couple of day

  • Hi, I have made this motion sensor :

    With HC-SR501 PIR Motion Sensor Module and a MQTT gateway

    and after a couple of day it stop working or become less accurate so i need to unplug it and plug it back so it start working fine again

    I unplug every connection and reconnect everything... i fix it up tight in my box so nothing move or unplug it self ..

    Do you have an idea what cause this ?

    @Dominic-Bonneau - I always start by swapping to another power supply if its a 5v version.

  • Hum ... it's Arduino pro mini 8v and i power it with USB and an apple power block.

    What should I do instead ?

    @Dominic-Bonneau - You mean a Pro Mini 5v? As i said I would change the usb charger to another and see what happens. Also I would make sure i have capacitors on the radio and the wiring/soldering is good.

    Sounds to me like power issue (long shot without more info) and somethings crash the radio.

    Please report with logs and sketches if possible.
