SEN0521, 5.8GHz Microwave Radar Module

The SEN0521 is a microwave sensor module. I can transmit electromagnetic waves and then determine the movement of objects based on the reflections.

This microwave sensor is a microwave module that can transmit the electromagnetic wave of 5.8GHz. It can detect the difference between the transmitted wave and reflection wave to judge whether there is an object moving in the detection area.

Different from the traditional sensors that can only judge human presence by detecting big body movements, this microwave sensor can perform well in detecting small movements like breathing so as to determine human presence even if the person is sitting or sleeping. The detected result can be output through the serial port or high/low level of the I/O port.

Featuring high reliability and sensitivity, and strong anti-interference, it is small and easy to integrate, which can be widely used in fields that require motion detection, such as lighting, security, home, home appliances, hotels, garages, buildings, traffic, etc.
