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, agriculture, smart home, security monitoring and other fields. Note: For technical support, please refer to the CQRobot Wiki to provides sample programs and user manuals, SKU: CQRSENWB02.

Note: There are ultra-high frequency MOS devices inside the microwave motion sensor. If you try to use battery power to test during the test, this can avoid the breakdown caused by the static pressure difference between the power supply and the test device, such as the oscilloscope; in addition, when the product is in use, Please try to choose battery power supply to ensure the best detection effect. It is used in industry, transportation, industry, agriculture, smart home, security monitoring and other fields. Can detects of non-living objects; The microwave moves at the speed of light with great directionality. Compatible with Raspberry Pi and Arduino Board. Non-contact detection; Adapts to harsh environments without affecting by temperature, humidity, noise, airflow, dust, light, etc. Powerful anti-RF interference capability; Low output power, no harm to human body; Long detection distance. The microwave motion sensor is a microwave moving object detector designed by the principle of Doppler radar. Unlike ordinary infrared detectors, microwave sensors detect the movement of objects by detecting the microwaves reflected by the object. The detection object will not be limited to the human body, but there are many other things.
