Does CG-LO linear Led Light offer microwave sensors as an option? What is the principle?

CG-LO linear Led Light does offer microwave sensors as an option. Microwave sensors are sensors based on the principle of microwave radiation. They detect and measure information such as distance, speed, and direction by receiving and processing microwave signals.
1. Basic characteristics of microwaves
Microwaves are a type of electromagnetic wave with wave-particle duality. Their basic properties are usually manifested in three characteristics: penetration, reflection, and absorption. When microwaves encounter objects of different materials during propagation, different interactions will occur. For example, for materials such as glass, plastic, and porcelain, microwaves almost pass through without being absorbed; for water and food, microwaves will be absorbed and heat themselves; and for metal objects, microwaves will be reflected.

2. Composition and working principle of microwave sensors
Microwave sensors are mainly composed of microwave oscillators and microwave antennas. Microwave oscillators are devices that generate microwaves. Their components include klystrons, magnetrons, or certain solid components. The oscillation signal generated by the microwave oscillator needs to be transmitted by a waveguide and emitted through an antenna. When the microwave sensor is working, the transmitting antenna continuously transmits microwave signals of a specified frequency. These microwave signals form an electromagnetic field in the detection area and cover an invisible volume detection area. When the object in the detection area moves, part of the microwave signal is reflected back to the sensor. After the sensor receives the reflected microwave signal, it converts it into an electrical signal and processes it by the measurement circuit.

3. Application of Doppler effect
Microwave sensors use the Doppler effect to identify moving objects using microwaves. The Doppler effect refers to the change in the frequency of the microwave signal received by the receiver when there is relative motion between the transmitting source and the receiving body. In a microwave sensor, if the object is stationary, the frequency of the reflected microwave is the same as the frequency of the transmitted microwave, and the sensor will not detect the movement. However, once movement occurs in the detection area, the reflected microwave changes frequency, and the sensor is able to detect this frequency change, thereby identifying the movement of the object.

4. Application and advantages of microwave sensors
Microwave sensors have many advantages, such as fast response, high accuracy, and contactless detection. Therefore, it is widely used in logistics, security, transportation, unmanned driving and other fields. In the field of logistics, microwave sensors can be used to track the location and speed of goods and improve logistics efficiency. In the field of security, microwave sensors can detect the presence of intruders and issue alarms in time to improve safety. In addition, microwave sensors can also be used in smart homes, automated production lines and other fields to achieve intelligent control and automated production.
