This is a 5.8GHz microwave radar module from DFRobot. The module can detect movement within a range of 11 meters using electromagnetic waves. Compared to traditional sensors that only detect larger body movements of a person, the microwave sensor is much more accurate. It can even detect the slightest movements, such as breathing, allowing it to identify individuals who are sitting or sleeping and otherwise not moving. The measurement data can be read via a serial or high/low-level IO port. The sensor can be used in various applications where a very precise motion detector is required.
