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:
It is widely used not only in human detection, but also in the detection of many other objects. It has the characteristics of long detection distance and high sensitivity, and is not limited by the ambient temperature. It is widely used in the fields of industry, transportation, civil liquid level, automatic door detection, automatic cleaning, production line material detection, etc.
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.
Attention
There is an ultra-high frequency MOS device inside the microwave motion sensor. When you are testing, please use battery power as much as possible to avoid breakdown that is caused by the static voltage difference between the power supply and the test equipment, such as an oscilloscope.
In addition, we suggest that you use battery power to ensure the best detection effect when you are operating the product.
