Hi, don’t use 1uF, use 150 - 220nF ceramic capacitors.
Then please write how it turned out. Nothing heats up.
Here is a pic of the switch that monitors all my PIRs for false ons. I went to work at 8.20am and came back at 3.20pm. Not a single false alarm…
In case of other false alarms, try another power supply, it is possible that it has bad voltage smoothing.
