YW204: Human Presence Detection

24Ghz Mmwave Human Sleep Sensor for Hotel Room Management

Redefine guest comfort and operational efficiency with our 24GHz mmWave Human Sleep Sensor, specifically designed for next-generation Hotel Room Management Systems. Unlike standard motion detectors that fail when a guest is sleeping, this ultra-sensitive radar detects the rhythmic micro-movements of breathing and heart rate. It ensures that the room remains “occupied” even during deep sleep, preventing the common frustration of lights or HVAC shutting off in the middle of the night.

>> Why Choose 24GHz mmWave?

Uninterrupted Comfort: Maintains personalized climate and lighting settings while guests are perfectly still.
Privacy-First Technology: Offers 100% privacy with no cameras or microphones, making it ideal for bedrooms and bathrooms.
Smart Energy Savings: Instantly triggers “Away Mode” only when the room is truly vacant, significantly reducing utility overhead.
Non-Intrusive Integration: Compact, sleek design that mounts discreetly on walls or ceilings without disturbing room aesthetics.

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.
