YW204: Human Presence Detection

Lorawan Presence Motion Detector for BMS Building Automation System

Maximize efficiency and precision in your smart environment with our LoRaWAN 24GHz Human Presence Motion Detector. Engineered for advanced Building Automation Systems (BMS), this sensor utilizes 24GHz mmWave radar technology to detect not just motion, but “true presence.” Unlike standard PIR sensors, it identifies micro-movements—such as breathing or typing—ensuring lights and HVAC stay active even when occupants are stationary.

>> Feature Highlights

True Presence Sensing: Detects static occupants with up to 99% accuracy.
Ultra-Long Range LoRaWAN: Low-power, long-distance wireless connectivity perfect for large commercial facilities.
Privacy-First: Accurately monitors occupancy without the use of cameras.
Smart Integration: Seamlessly automates lighting, climate, and space utilization via your BMS.
Eco-Efficient: Drastically reduces energy waste by eliminating false “empty room” triggers.
Dimensions: L61mm x H40mm

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.
