Control lights intelligently and accurately with high sensitivity and high antiinterference capacity. Apply motion sensing technology to detect human motions in a detection area. Support sensor grouping function to easily control multiple lights from one location. Run on the Bluetooth 5.0 SIG Mesh system; Link with other Bluetooth devices to trigger cloud scenes and advanced lighting control. Support execution of local scenes without a gateway or the Internet needed, which run faster and stably. Turn relay turns on/off, making sensors ideal for corridors, stairways, offices, etc. Use zero-crossing detection technology so current flowing through the relay contacts is close to zero at the moment when the relay is turned on or off, effectively improving the lifetime of a relay. Ceiling mounted sensors fit well for homes, offices, shopping malls and more to easily achieve smart lighting control. Easily set parameters via dip switches, the infrared remote, or via the mobile APP.
