Digital Intelligent Passive Infrared Sensor AM412
AM412 is a new digital intelligent PIR sensor. This Smart digital detector offers
a complete motion detector solution,with all electronic circuitry built into the
detector housing. Only a power supply and power-switching components need
to be added to make the entire motion switch, a timer is included.
