#58096 Hi!

I've read a lot about the interferences of the ESP radio on the PIR Sensor, but there isn't a clear solution. I have a lot of false positives so my design doesn't work propoerly.

One solution could be low the power level of the radio broadcast, but I don't know how to do this.
Any idea?

Thanks a lot! :)

#58621 I had a similar issue of false positives from a PIR when used together with ESP8266. Managed to solve it by putting an RC filter on the 3.3V supply to the PIR (100 ohm resistor feeding a 100uF electrolytic capacitor in parallel with 100nF ceramic). The PIR triggers based on mV differences from two thermopiles, so I surmise it is may be sensitive to supply fluctuations which can be generated when the ESP8266 communicates.
