GH-100 GH100 Microwave Sensor Module For Various Fields Such As Anti - theft Automatic Sensor Doors Automatic Aensor Lights Traffic Speed Measurement Intelligent Control

• Product Features:
  • Non - contact Detection: It can detect the movement of objects without physical contact.
  • Environment - friendly: Its detection is not affected by factors such as temperature, humidity, noise, air flow, dust, and light, making it suitable for use in harsh environments.
  • Strong Anti - interference Ability: It has strong resistance to radio - frequency interference, ensuring stable operation.
  • Low - power and Safe: The output power is only 5 mW, which poses no harm to the human body.
  • Long Detection Range: The detection range can exceed 20 meters.
• Working Principle:
  Based on the Doppler effect, when radio waves encounter a moving object, they will be reflected, and the frequency of the reflected waves will change with the movement of the object. If the object moves towards the transmitter, the frequency of the reflected waves will increase; otherwise, it will decrease. The sensor detects the movement of the object by sensing the change in the frequency of the reflected waves.
• Package and Interface:
  The size is 48.5 x 63 mm, and it adopts a gravity 3 - pin interface (digital).
• Application Scenarios:
  It is mainly used in automatic door control, safety protection systems, automatic video control systems, and can also be used in vehicle speed measurement, liquid level detection, production line material detection, car reversing sensors and other industrial, transportation, and civil fields.
