Motion Sensor PIR (Passive Infrared Sensor) Light Switch

The motion sensor PIR light switch senses when to turn on your lights by detecting when you’re in the room – and turns the lights off when you’re not.

The PIR energy saving system measures natural infrared light radiating from people in its field of view. The motion sensor PIR light switch has been proven to reduce around 128 hours of unnecessary lighting per year in an average home and should save around 10% of the electricity you use on lighting in the home each year (based on average use).

The unit also detects light levels entering the room, so it will only switch on lighting when the room is dark and the sensitivity is adjustable. The sensor covers 180 degrees by 8m long. There is no on/off button as the DYB switch sensor can be configured to check a certain level of movement before activating.

Simply put, if there is no-one in the room the unit will switch itself off, but don’t worry about constantly having to wave your arms around to keep it running! The PIR Energy light switch is quickly and easily installed by K&L’s electricians, please contact us for more information or for a free home safety survey.
