Fit a motion sensor light switch to automatically switch off lights when a room is empty
- The Motion Sensor Light Switch is a new product which will only turn lights on in a room when it is occupied. By automatically turning off the lights when no-one is in the room, the manufacturers claim that an average of 128 hours per year of unnecessary lighting will be avoided, reducing electricity consumption for the lighting by 10%.
- The light switch is sold as a complete, easy to install unit which can be quickly fitted as a direct replacement for a standard (non-dimmer, single way) switch. A manual switch is provided so that lights can be switched ON or OFF, or to enter AUTO mode. When in AUTO mode, the fitted PIR sensor (which covers 110 degrees with a range of 5 metres) detects if someone is in the room. A second adjustable light sensor ensures that the lights are only turned on when it is dark
- A delay time setting (8 secs to 6 mins) is provided so that you can set how often you want the motion detector to check the room for inhabitants. The longer this time is set, the longer the lights will remain on after you leave the room. The shorter the time, the more likely it is that the lights will turn off while you are still in the room - potentially a problem if you are sat in an armchair not moving or walking backwards and forwards directly towards the motion sensor.
