YW204: Human Presence Detection

24Ghz Radar KNX BMS Occupancy Sensor for Building Automation

Optimize your facility’s intelligence with 24GHz Radar KNX BMS Occupancy Sensor, the professional-grade solution for sophisticated Building Automation. Engineered for seamless integration into the KNX ecosystem, this sensor utilizes high-frequency mmWave technology to detect “true occupancy”—including stationary individuals—where traditional PIR sensors fail.

>> Why Choose 24GHz mmWave?

Total Room Coverage: The top-down ceiling perspective eliminates blind spots caused by furniture or partitions.
Native KNX Compatibility: Direct connection to the KNX bus for decentralized control of lighting, HVAC, and shading systems.
Static Presence Detection: Advanced 24GHz radar senses micro-movements like breathing and typing, ensuring lights never shut off on focused occupants.
Ambient Light Sensing: Features a built-in lux sensor to ensure lights only activate when the natural daylight is insufficient, maximizing energy savings.

Human Presence Detection:

24Ghz microwave motion sensor detects human existance rather than only movements. No matter if the person sits/stands statically or turns their back to the sensor. The microwave lifebeing sensor can accurately recognize its presence and keeps the lights on. When the movement is detected, the load switches on. If no more movement is detected within a certain time period will switch the load off.

At the same time, the human presence detector effectively mitigates airflow interference caused by air conditioning and exhaust systems, ensuring accurate identification of human occupancy.

Our applications are healthcare, general offices, corridors, washrooms, classroom and conference rooms.

Human lifebeing microwave sensor offers human centric lighting controls by detecting movement, subtle motions, and breathing for static state detection.

* Movement signal: Human movement within the detection area.

* Subtle motion signal: Captures minimal actions like leaning, body swings, head movements, typing, or phone interactions within the detection area.

* Breathing signal: Detects breathing signals, including dilation in the abdominal and chest cavities.
