60GHz mmWave Radar Sensor for breathing rate and heart rate, vital sign monitoring, IR60BH1A
IR60BH1A 60GHz mmWave radar module applies FMCW detecting theory to implement simultaneous personal breathing rate and heart rate detection with high accuracy (over 90%), providing a fully total and secure environment (It’s contactless, no harm to the human body), independently from other interfering factors. This is a standard bio-radar sensor for consumer electronics, healthcare as well as industrial applications.
Features
- Radar detection based on FMCW signal
- Realize synchronous perception of human breathing rate and heart rate
- The detection distance of breathing and heartbeat is 0.4-2m
- Low output power, no harm to the human body
- It is not affected by temperature, humidity, noise, airflow, dust, light, and other environmental factors
- The product supports secondary development and adapts to a variety of scenario
- General UART communication interface, providing general protocol
- Four groups of I\O are reserved, which can be input and output according to user-defined or simple interface simulation
