MR24BSD1 24GHz mmWave Sensor - Respiratory Sleep Detection Module

The MR24BSD1 24GHz radar module applies Doppler radar detection technology to provide human sleep quality monitoring, detecting body movement and being stationary along with human breathing rate, providing a fully private and secure environment. It provides useful privacy-protected, secure sensor radar systems in smart home applications like sleep safety alarms, sleep respiratory detection, and movement monitoring.

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

The MR24BSD1 radar leverages the performance of the 24GHz mmWave to monitor human sleep quality implements based on received breathing rate and body movement while people are asleep. Furthermore, the radar is independent of temperature, humidity, noise, airflow, dust, light, and other environmental influences. Designed with a low power output, the radar maintains a health-friendly working status while it is detecting.

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 detects 1.5 meters of body movement and 1.5 meters of human breathing rate.
