First, the working principle of microwave radar induction module
The principle of microwave radar induction module is to realize object detection and tracking by using the characteristics of electromagnetic wave transmission in space. The frequency of this electromagnetic wave is generally between 5.8GHz and 24GHz, so the technology is also known as microwave RF technology. The working principle of microwave radar induction is roughly as follows:
1. Microwave signal emission
Microwave radar sensor module will emit a certain frequency, power and time length of the microwave signal, the process is similar to the transmission of a series of voice signals.
2. Microwave signal propagation
The transmitted microwave signal will encounter the surrounding object in the process of propagation, and the object's reflection, scattering and absorption of the microwave signal will depend on the nature and shape of the object.
3. Microwave signal reception
The microwave radar sensor module receives all the microwave signals that travel back. These signals may be converted into electrical signals and picked up by a receiver.
4. Signal processing
The received signal is processed by the signal processing module to convert it into distance or other target parameters. Finally, the microwave radar sensor module identifies and tracks objects based on these parameters.
Second, the application of microwave radar induction module
Microwave radar sensor module has a wide range of applications in many fields, the following are some common application areas:
1. Wireless communication
