The KN-4in1-CL 4-in-1 Sensor is a smart, ceiling-mounted multifunction device designed for KNX automation systems. It integrates temperature, humidity, brightness, and motion detection into one compact sensor, enabling precise environmental monitoring and intelligent control of lighting, HVAC, and scene automation. With a detection radius of φ5–7 meters and installation height of 2.5–3 meters, it ensures accurate and reliable performance in modern residential and commercial smart building environments.

The KN-4in1-CL 4-in-1 Sensor is an advanced multifunction environmental sensor engineered for high-end KNX smart home and building automation systems. Designed for ceiling installation, this compact unit combines four essential sensing technologies—temperature, humidity, brightness, and motion detection—into a single intelligent device, providing comprehensive environmental monitoring and automation control.

This 4-in-1 smart sensor enhances the efficiency and comfort of indoor spaces by enabling automated control of HVAC systems, lighting, shading, ventilation, dimming systems, and customized scene settings. Its integrated PIR motion detection ensures responsive lighting control and occupancy-based automation, while its brightness sensor allows daylight-dependent lighting adjustments for optimal energy savings.

The temperature and humidity sensors continuously monitor the indoor climate, allowing the automation system to maintain comfort and regulate HVAC equipment with precision. Designed with a detection radius of φ5–7 meters and an installation height of 2.5–3 meters, the KN-4in1-CL guarantees optimal performance in homes, offices, hotels, hallways, conference rooms, and commercial buildings.

Powered by the KNX bus (21–30V DC, max 12mA), the sensor ensures seamless communication and stable integration with all KNX-certified automation devices. Its minimalist design and advanced functionality make it the perfect choice for smart building projects requiring reliable environmental monitoring and intelligent control.
