Microwave Sensor Module

  • Doppler radar microwave motion sensor is the use of design principles of the microwave detector moving objects.
  • Unlike infrared detector, microwave sensor by detecting the object by the reflected microwaves to detect movement status of the object, and the object will not be limited to the detection of the human body, there are many other things.
  • Microwave sensor is not affected by the ambient temperature, the detection distance, high sensitivity, is widely used in industry, transport and civil means, such as vehicle speed, automatic doors, sensor lights, reversing radar.
  • Because microwave sensor detects the presence of objects universality, in real life applications, with another sensor will do targeted testing.
  • The microwave sensor + infrared pyroelectric sensor, can effectively determine whether someone passes will not be the sun, the color of clothing to be disturbed, nor will other objects react.

Product Features
This detection method compared with other detection methods have the following advantages:

  • Nontocontact detection;
  • Independent of temperature, humidity, noise, air, dust, light and other effects, suitable for harsh environments;
  • RF antitointerference ability;
  • Output power is small, do not constitute harm to the human body;
  • Detection distance;
  • Capable of testing the class of nontolife objects
  • Microwave directional well, speed is equal to the speed of light;
