WiZ Wireless Sensor w/Batteries operates the room"s light sources automatically thanks to its smart motion detector that detects movement within a distance of up to 3 metres. The sensor can be placed near the room"'s entrances so you have light as soon as you enter. As with all WiZ products, the sensor is smart-based and can be controlled via the WiZ app. Here you can set the light time and desired light type or use the Tunable White function to switch between different light settings depending on the time of day.
