In this paper, the working principle of microwave radar induction switch will be analyzed in detail to help readers understand its technical characteristics and application advantages.

Overview of microwave sensors

Microwave sensor, also known as microwave radar sensor, is a kind of induction device based on the principle of microwave Doppler effect. It uses the transmission and reception of high frequency electromagnetic waves (microwave) to realize the non-contact detection of target objects. Microwave sensor has the characteristics of high sensitivity, strong anti-interference ability, wide application range, etc., especially suitable for all kinds of scenes requiring automatic induction control.

Second, the working principle of microwave radar induction switch

Microwave radar induction switch is mainly composed of microwave transmitter, receiver, signal processing circuit and control circuit. Its working principle is roughly as follows:

Microwave transmission and reception

The microwave radar induction switch transmits microwave signals of a certain frequency through the microwave transmitter, and these signals propagate in the form of electromagnetic waves in space. When the target object (such as human body, vehicle, etc.) enters the detection range of the microwave sensor, it will reflect part of the microwave signal. The receiver is responsible for picking up these reflected microwave signals.

Signal processing

The reflected signal received by the receiver is processed by the signal processing circuit, which mainly includes the signal amplification, filtering and demodulation steps. The processed signal can extract the distance, speed and other information of the target object, which provides a basis for the subsequent induction control.

Control circuit and trigger mechanism

According to the information of the target object extracted by the signal processing circuit, the control circuit will determine whether it is necessary to trigger the switch action. In general, when the target object moves within the detection range, the microwave sensor will detect the Doppler shift phenomenon, so as to determine that the object is active. When the movement of the moving object meets the preset conditions (such as moving speed, moving distance, etc.), the control circuit will issue instructions to trigger the switch action, such as opening the lighting equipment, starting the security system, etc.

In addition, the microwave radar induction switch usually has a delay function, that is, after triggering the switch action, it will remain open for a period of time, so that the target object can continue to maintain the switch state when it is active in the detection range. When the target object leaves the detection range or stops moving, the switch will be automatically turned off after the end of the delay time, so as to achieve the purpose of energy saving and environmental protection.
