      The principle and application of the advantages of the microwave sensor radar module solution:


      First, the principle of microwave sensor

      The principle and application of the advantages of the microwave sensor radar module solution

      1. The basics of microwave

      Microwave has the characteristics of straight line propagation, convenient reflection, poor diffraction ability, good transmission performance, and is not easily affected by other electromagnetic waves, smoke, flame, dust, temperature and so on. A microwave sensor is a sensor that uses the characteristics of microwaves to measure information such as target movement, distance, speed, direction, and presence. The basic principle is that microwaves are radiated into free space through a transmitting antenna. When free space electromagnetic waves encounter a moving object, part of the electromagnetic energy is reflected from the surface of the moving object to the detector receiving antenna, and the receiving antenna receives the reflected microwave signal and detects the reflection through the signal processing line. Wave electromagnetic parameters to realize microwave sensing function.


      2. Operation mode of microwave sensor

      Microwave sensors mainly include CW (continuous wave) and FMCW (frequency modulated continuous wave). CW (Continuous Wave) can detect the movement and speed of the target. FMCW (Frequency Modulated Continuous Wave) can detect movement, speed, distance and presence of targets.


      Several advantages of microwave sensor radar module solution


      1. Intelligent induction:

      When someone enters the induction detection area (within a diameter of 10-16m), the light will automatically light up; when no one walks within the detection range of the sensor, the sensor enters the delay time, and the light will automatically turn off when the delay time expires (if someone walks, the light will turn off again. lights up).


      2. Intelligent identification:

      To put it simply, the automatic recognition and detection of sunlight can be set to be off during the day, and it will be on at night when there are people; it can also be turned on at any time as needed.


      3. Anti-interference:

      As we all know, there are many signals of different frequencies in space (such as 3GHz signal of mobile phone, 2.4GHz signal of wifi, 433KHz signal of TV remote control, sound wave signal, etc.). Some of the signals are similar to human-induced signals. Our radar module solution products can intelligently identify useful human body sensing signals, prevent false triggering of lights from other interference signals, and ensure product reliability.


      4. Strong applicability:

      1) The microwave radar sensor can penetrate ordinary glass, wooden boards, walls and ceilings. When installed, the detection coverage can reach 360 degrees, the diameter is 14m, and it is not affected by harsh environments such as temperature, humidity, dust, etc.; it is widely used in study, corridor, corridor, garage, warehouse, basement, elevator entrance, doorway and other indoor lighting places.

      2) The radar module solution is suitable for load control of ordinary ceiling lamps, fluorescent lamps, three-proof lamps, and LED lamps. Almost all lighting lamps can be used; it is connected to the original circuit in series, small in size, hidden in the lamps, does not occupy space, and is simple and convenient to install.


      5. Energy saving and environmental protection:

      1) Radar module solution The standby power consumption of the module product itself is 1mW, and it starts at zero level, so as to protect the service life of the sensor.

      2) The intelligent control lamp can be turned on and off automatically, and it can be turned on when necessary, which is more conducive to energy saving and consumption reduction.

      3) Some people worry about microwave radiation, you can use it with confidence. The microwave power of the product is less than 1mw (equivalent to 0.01% of the mobile phone radiation).
