Tuote SRC323995. RCWL-0516 microwave radar motion sensor. Module uses a “microwave Doppler radar” technique to detect moving objects. Its advantage over traditional PIRs is that it can detect presence through obstacles with a sensing distance of 3m average in real life conditions. Vcc is 5VDC do not use higher voltage. Logic level output "HIGH" when active. A lot of information in web. Some links at "instructions".
