Order information

24GHz human body monitoring microwave radar module is a kind of detection module based on the Doppler radar principle, which realizes the human body’s biomotion sensing and the human body’s biosensing. It can realize wireless sensing of personnel status in a specific place by sensing the Doppler parameters of human movement as well as physiological parameters of personnel. The module adopts FMCW FM Continuous Wave and innovative human body sensing algorithm, which is compatible with ceiling and wall mounting, detects the set space, senses the presence of people, and communicates with the main control system in real time, which makes the connection between things and people smarter and more humanized.

In addition, the microwave radar module is better than the infrared sensing module sensing distance, wide angle, no dead zone lens and lens aging problems, not affected by temperature, humidity, airflow, dust, noise, light and dark. The module also integrates high performance 32 bit MCU, powerful performance, rich algorithms, scalability, suitable for high performance requirements of the scene. At the same time, support standard UART interfaces, can be interconnected with other master controllers or sensors, can also be used as master controllers, and can be based on the detection of human respiration, to realize the presence of sensing.
