5.8GHz Doppler Effect Microwave Motion Sensor

Description

The microwave motion sensor is a microwave moving object detector which is designed

according to the principle of Doppler Radar. This differs from the method used by a regular

infrared (IR) sensor as microwave is sensitive to a variety of objects that are microwave-reflective,

and its sensor readings are not affected by the ambient temperature.

Comparison with IR Sensor:

CQRobot launches 5.8GHz Doppler effect microwave motion sensor (CQRSENWB02), built-in

sensor - AT5820 microwave radar chip. The AT5820 chip integrates a high-performance

microwave radar transceiver and MCU, which can be interconnected with other main controllers

or sensors, and filter out clutter interference through algorithms. It is not only widely used in

human body detection, but also widely used in the detection of many other objects. With the

characteristics of long distance and high sensitivity, it is not limited by the ambient temperature.

It is used in industry, transportation, industry, agriculture, smart home, security monitoring and

Page 2 other fields. The detection objects of the microwave sensor are universal. When it comes to the actual use in life, we will usually match it with another sensor for targeted detection. For example, a combination of microwave sensor and infrared pyroelectric sensor. It can accurately judge whether someone is passing by without being disturbed by sunlight and clothing color, and will not react to other objects.
