Re: weird problem: PIR sensor positive on wifi activity

I have exactly the same problem with a Raspberry PI Model B, an edimax EW-7811UN wifi dongle and an HC-SR501 PIR sensor.

Putting some tinfoil between the Pi and the PIR seems to resolve the issues for me. However I will look for a USB extension cable to be on the safe side.

Thanks for the solution!
