The DETECT ME 3 motion detector has a square black plastic housing, with a height of 10cm and a length of 10cm. The sensor features IP44 protection against spray water to ensure it is suitable for outdoor areas such as gardens or driveways. With this separate device, lights with no sensor can be switched on by motion detection, enabling poor visibility areas to be lit when needed and deter unwanted visitors. The integrated twilight sensor gauges the ambient light level to ensure the light only switches on when needed.
