1,21 €
The RCWL-0516 is a Doppler radar microwave motion sensor module using the RCWL-9196 IC which is an alternative to a PIR motion sensor such as the HC-SR501 or HY-SRF05. Instead of sensing changes in infrared emitted by a moving person, this sensor uses a microwave Doppler radar to detect moving objects.
