SENSKYSensky BS033C 110v Motion Sensor Light Switch, 180 Degree View Occupancy Sensor Switch, Wall Sensor Switch Light Sensor,Single Pole (Neutral Wire Required), White
Main highlights- 【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 and Energy-saving】: 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.Motion sensor switch uses a passive infrared (PIR) sensor to energy-saving and lower bills.
- 【Sincerely seller service】: We have 24-hour customer service. If you encounter any problems in use, we are always waiting to serve you.
- 【Rated Load】: 1200W/220v (incandescent lamp)300W/220V (energy-saving lamp) 400W/110V (incandescent lamp)400W/110V (incandescent lamp)
- 【Neutral Wire Required Installation】:Compatible with 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.
