The microwave motion sensor is a microwave moving object detector which is designed according to the principle of Doppler Radar. It is widely used not only in the detection of human body, but also many other objects. It has the characteristics of long detection distance and high sensitivity, and is not limited by ambient temperature. It is widely used in industrial, measurement, liquid level, automatic door movement detection, transportation and civil fields. Note: For technical support, please refer to CQRobot Wiki to get the test code, SKU: ? CQRSENWB01.

DISTRIBUTION LIST 1 * Microwave Motion Sensor 1 * Ocean Interface JST 3-Pin CableNote: 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. Used in industrial, transportation and civil applications such as measuring, liquid levels, automatic door motion detection, automatic washing, production line material detection and car reversing sensors etc. 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.
