YW204: Human Presence Detection

Microwave Human Presence Motion Detection Sensor for Light Switch

Upgrade your lighting control with our Microwave Human Presence Motion Detection Sensor, designed to replace outdated PIR switches with high-performance 24GHz mmWave technology. This intelligent switch eliminates the frustration of lights turning off while you are still in the room, detecting the tiniest micro-movements like breathing or typing.

>> Why Choose 24GHz mmWave?

Total Presence Sensing: Unlike infrared, microwave signals detect “static” occupants, ensuring consistent illumination in offices, bathrooms, and kitchens.
Invisible Installation: The sensor can be mounted behind plastic covers or decorative faceplates for a completely seamless, minimalist look.
Adjustable Sensitivity & Delay: Fine-tune the detection range to prevent the sensor from seeing through walls into adjacent hallways.
Broad 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.
