Motion Detection Function The MiNi PIR infrared pyroelectric sensor has the capability to detect movement, capable of sensing the movement status of moving individuals within the sensing area, suitable for smart control scenarios such as automatic lighting. Seamlessly Interfacing with the KNX System By integrating with the KNX protocol, this sensor can seamlessly integrate into the KNX system, enabling intelligent control of lighting devices, including smart switches, dimming, and full utilization of natural light. No auxiliary power supply required, can be connected directly. The flexibility and intelligent control capabilities of the sensor, combined with the integration of the KNX protocol, make it an ideal choice for smart lighting control, bringing efficient and energy-saving lighting management to various KNX projects.Built-in Digital Illuminance Measurement Chip This product has a built-in 0-32000Lux digital illuminance measurement chip, capable of simultaneously detecting ambient light, meaning the sensor can monitor ambient light intensity, realize monitoring and control of light intensity to adapt to different lighting needs.
