Compared to the traditional PIR sensor, 24GHz mmWave sensors offer the better performance of human activities detection for high sensitivity. The transmitting mmWave is millimeter-level which means mmWave sensors will maintain sensing status even if there is a shelter block the detected object. Unlike rapid responding to PIR sensor, mmWave sensors detect objects continuously. All of which makes mmWave sensors quite useful in the living rooms, hotels, or even prison that requires monitoring all the time.

The MR24BSD1 radar leverages the superior performance of 24GHz mmWave to monitor human sleep quality implements based on received breathing rate and body movement while people falling asleep. Furthermore, the radar is independent of temperature, humidity, noise, airflow, dust, light, and other environmental influences. Designed as low power output, the radar maintains health-friendly working status while it is detected. For privacy protection, the radar uses the properties of millimeter waves that only process wave signals to provide a fully private sensing environment.

The radar supports secondary development and it adapts to various scenarios applications as it includes scene recognition capability that identifies occupied/unoccupied and personnel activity status. The detected area is a Horizontal 40°/vertical 40° sector beam and it maximum detect 1.5 meters of body movement and 1.5 meters human breathing rate.
