Neutral Wire Required Installation: Three wires (Black, Green and Red). Black wire goes to Hot; Green wire goes to Neutral; Red wire goes to the hot end of your light (the load). Then the other end of the light and the green wire of the switch go to the Neutral. Please also see pictures carefully before you install to avoid causing any false alarm.
Motion Sensor & Light Sensor Switch: Automatically turn on/off lights based on room occupancy when detect hear source and environment brightness. Detection motion speed is 0.6~1.5m/s.
Time Delay: Adjustable Time-Delay for customizing: Min: 10sec±3sec ; Max:7min±2min (The load will stay on for the time you set, then go out).
Three Mode: AUTO mode works as an occupancy sensor (Auto ON, Auto OFF). ON and OFF modes allow you to override the sensor and use the sensor switch as a regular light switch.
Energy-saving: Motion sensor switch uses a passive infrared (PIR) sensor to energy-saving and lower bills.
