Battery-powered Homematic IP motion and twilight sensor for outdoor use This sensor for use outdoors, which is powered by two replaceable batteries for up to three years, detects both movements and the ambient brightness. This makes it perfect for linking with alarm sirens and components for lighting control. Therefore, the passive infrared motion sensor is perfect for monitoring tool sheds, for example. When it is triggered by an intruder, it triggers not only the connected siren, but also a push message to your smartphone, if required. It is also possible to activate an outdoor wall light, which is turned on by the Homematic IP radio actuator.
