How it works?
It run on battery. will use PIR functions. but turn to mmwave radar features once motion detected.then can detect moving or non-moving.
compared with other human presence sensor,it just run battery only. don't have USB port to power up.but to save battery.it just use PIR features in normal time. once motion detected,it use mmwave radar features.
