Sensky BS033C 110v Motion Sensor Light Switch, 180 Degree View Occupancy Sensor Switch, Wall Sensor Switch Light Sensor (Neutral Wire Required), White

【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.
【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 provide warranty service】: We have 24-hour customer service and warranty service for you. If you encounter any problems in use, please feel free to contact us, we are always waiting to serve you.
As there is a photosensitive internal, switch only allows the light switch to be activated on in dark condition.
So when you test the switch on AUTO function in a very bright environment (Ambient Light: > 5-10LUX) , It won't work ( Even movement sensed).
In this condition, Please do Cover the detection area with your hand for about 30 seconds then test again.

Note
Time -delay is added continually: When it receives the second in induction signals after the first induction, it will compute time once more on the rest of the first time-delay basic (set time).
Currently the temperature becomes lower, the sensitivity of the sensor would become higher, so the probability of false triggering the sensor turning on increases. We recommend to reduce the Lux value appropriately to reduce triggering motion sensor. If the switch works error, please don't worry. Any questions or needs welcome to contact us.
Attention:

1.Don't exposed to direct sun light or lighting, big wind, near a heater or air condition.

2.Don't fix it at a place where there are obstructing material (e.g. Glass, dense clothes) which IR cannot get though.

3.Don't fix it in strong shock or vibration environment.
