Apply motion sensing technology to detect human motions in a detection area. Running on the Bluetooth 5.0 SIG Mesh system, the sensor outputs DALI or 0-10V dimming signal and support wired and wireless control. Work with a smart gateway to trigger cloud scenes or advanced lighting linkage, making application scenarios enriched. Support execution of local scenes without a gateway or the Internet needed, which run faster and stably. Support sensor grouping function to easily control multiple lights from one location. Control lights intelligently and accurately with high sensitivity and high anti-interference capacity. Turn relay turns on/off and support 2-step dimming and 3-step dimming, 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.
