When triggered, the Lightwave RF Wireless PIR Movement Detector/ Sensor will activate any number of Lightwave RF devices such as Dimmer Switches or Power Sockets. A variable delay period can be set after which those paired Lightwave RF devices then turn themselves off again. The PIR has many energy saving & security applications, such as in areas which are rarely used but require automatic lighting or electric heating for short periods. It is battery operated & wireless & therefore can be located anywhere indoors.
