Hi Guys,
i was just wondering if anyone has some experience with building their own PIR sensor.
and then could share that experience!
are there some know good/bad PIR’s?
and what would be the best way to link it to pimatic? i was thinking about either RF or ESP8266.
my final goal:
Cheap, small as possible, good working with pimatic.
and of course having fun building it 
So anyone any idea’s?
