24Ghz Microwave Motion Sensor

24Ghz Microwave Motion Sensors with 5 Year Warranty

YW204: Human Presence Detection

Smart Home Room Ceiling Presence Detection Lighting Controls

Enhance your home’s intelligence with our Room Ceiling Presence Detector. Designed for flush-mount or surface-mount installation, this ceiling sensor utilizes advanced 24GHz mmWave radar to provide 360° coverage that standard motion sensors simply can’t match. It doesn’t just look for “movement”—it detects your actual presence detection, keeping the lights on while you’re sleeping, reading, or working at a desk.

>> Why Choose 24GHz mmWave?

Total Room Coverage: The top-down ceiling perspective eliminates blind spots caused by furniture or partitions.
True Presence Logic: Say goodbye to “waving your arms” to turn the lights back on; our sensor detects the subtle micro-movements of breathing and heartbeats.
Ambient Light Sensing: Features a built-in lux sensor to ensure lights only activate when the natural daylight is insufficient, maximizing energy savings.
Smart BMS Integration: KNX, DALI, Rs485,Modbus, Tuya, Zigbee, Bluetooth etc.

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.
