Difference from traditional human PIR infrared sensor PIR infrared sensors can only detect human motion, but cannot detect when people are still, and the false alarm is serious. The human presence sensor adopts the principle of microwave, and has the functions of human presence, human stillness, human micro-motion and human motion detection. Can detect the brightness of the light Package Included: Human presence sensor xl instruction x1 Notes: Installation Notes a.
