Microwave Sensors detect movement by sending out electromagnetic pulses and measuring the changes in frequency due to reflecting off- a moving object.
How it works?
Choosing between presence and absence detection can make a significant difference to user-friendliness and energy saving. With presence detection, all movement is detected (including that from trees and animals if installed outdoors).
Presence Detection (auto ON and auto OFF)
Absence Detection (manual ON and auto OFF)
