Motion Sensor Light Switch
Motion Sensor Light Switch
Fit a motion sensor light switch to automatically switch off lights when a room is empty
lighting | energy efficiency | shopping
The
Motion Sensor Light Switch pictured above 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 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 (see image below).
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.

The light switch pictured above (
Timeguard ZV810) has more advanced features and is available for just under £30. If offers a
light on time adjustable from 6 secs to 12 mins, a wide 180 degree detection angle, and can switch up to 500 Watts of incandescent light bulbs or 150W of low voltage spotlights. Click here to view the

Reviews of Motion Sensor Light Switches
Since domestic
motion sensor light switches are still quite new products it is well worth reading about the experiences (often disappointing) of those who have fitted them in their homes: e.g.

Don't know if you know or not, but now they make a pir that required no neutral, so even for single gang switches with no neutral it can be controlled via a pir. 240v charges an internal battery which in turn runs the electronics, this also has many different time settings and lux settings. Cp electronics supply these pirs.

Thanks Dean,
The wall mounted presense detector (PIR) pictured above is the PDS from CP Electronics which requires no neutral connection thanks to the integrated relay. The switch can be used for lighting, heating, and ventilation loads.
