YW204: Human Presence Detection

24GHz Human Presence Motion Sensor for Micro-Motion Movement and Breathing Detection

The 24GHz Human Presence Motion Sensor is a highly sensitive radar module designed for detecting micro-movements and breathing signals, enabling accurate human presence recognition even when the person is stationary. Operating at 24GHz FMCW frequency, it captures subtle motions such as chest expansions from breathing, slight body sways, and minimal gestures like typing or head movements. This advanced sensing capability makes it ideal for applications in elderly care, security, and smart home automation where true presence detection is essential.

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.
