Description
The R60AFD1 radar module uses 60GHz mmWave radar technology to achieve the functions of human activity detection including moving, falling, and stationary. Based on the FMCW radar system and 1 transmit 3 receive (1T3R) antenna, the radar through the algorithm accurately scans the body tomography, achieving the fall detection function by height difference and speed change of the human body.
The module is suitable for top installation, and the detected area is a three-dimensional sector of 60° horizontally and 60° tilted and the measured distance is between 0.4 -3 m.
The radar supports secondary development and it adapts to various scenarios and applications. Using a universal UART communication interface provides an extra common protocol as 4 groups of I/O are reserved by the users definition. It can also be equipped with a host computer to output detection status and data, and its several groups of GPI
Os can be customized and developed by users.
Note:
1. The radar is designed to be used for individual (human body) in the environment, if there are multiple targets, it will affect the accuracy and precision of the radar.
2. The LED on the module has been removed.
3. The 60GHz radar baud rate is 115200.
Applications

Pinout
Interface 1:
The 5V pin is the power supply interface for the sensor.
RX and TX are the data transmission interfaces for the sensor. RX means serial receive and TX means serial transmit.
The human presence status output interface. You can use the level of these two pins to determine the current human movement in the environment.
GP2 output: high level - occupied, low level - unoccupied.
GP1 output: high level - active, low level - stationary.
Interface 2:
Flash firmware pinout: GND/ 3.3V /SWD/SWC
Overhead input/output pins: GP3~GP6.
