Pin Definition
The ME72MS02 is a 60GHz millimeter-wave radar module designed for non-contact respiration and heart rate monitoring. It integrates a 57–61GHz RF transceiver, 2T2R PCB microstrip antennas, 1MB Flash, a radar signal processing unit, and an ARM® Cortex®-M3 processor.
Based on FMCW (Frequency Modulated Continuous Wave) radar technology and advanced signal processing algorithms, the module detects radar echoes reflected from the human body to perform real-time measurement of respiration rate and heart rate for a single person.
The module can simultaneously detect:
· Respiration rate
· Heart rate
· Body movement
· Target distance
