Microwave sensor module is a sensor module that uses microwave signals for object detection. It can use microwave signals to sense objects in the environment and is widely used in fields such as safety sensing, remote ranging and trigger control. Although microwave induction modules have many advantages, they also have some shortcomings. In this article, we will discuss the working principle, advantages and disadvantages of microwave sensor modules to help users better understand its scope of application and precautions. How the microwave sensor module works The microwave sensor module mainly includes antenna, microwave source, transceiver module and signal processing module. Its working principle is as follows: 1. Send microwave signals The microwave induction module will send microwave signals of a certain frequency to the surrounding environment. These signals propagate in the air and will be reflected back when encountering objects. 2. Receive reflected signals The receiving module receives the microwave signal reflected back by the object, converts it into an electrical signal and sends it to the signal processing module for processing. 3. Process signals The signal processing module will amplify, filter, compare and other processes on the received reflected signals, and finally output the corresponding detection results. Advantages of microwave sensor modules 1. Able to adapt to a variety of environments The microwave induction module can work normally under various lighting conditions. Whether in a well-lit, dimly lit or completely dark environment, the movement of objects can be accurately perceived. 2. High reliability The microwave sensor module can operate normally under various extreme conditions, including high and low temperatures, dryness, humidity and other harsh environments. Its performance is more stable in severe weather in outdoor scenes. 3. Quick detection Because the microwave sensor module uses high-frequency microwave signals, it can sense the movement of objects. Compared with traditional infrared sensing modules, the microwave sensing module can respond faster and has a wider detection angle. 4. High flexibility The microwave sensor module can set different detection ranges, sensitivities and detection times to adapt to different application scenarios, such as access control, garage control, security monitoring and other scenarios. 5. Can pass through materials The microwave induction module can perform penetration detection on some non-metallic materials, such as walls, glass, etc., and has a wider range of applications. Disadvantages of microwave sensor modules 1. Limited detection ability of small objects The microwave sensor module has poor detection capabilities for small-sized items, and the detection of discarded items and some non-degradable items is not as accurate as the infrared sensing module. 2. Large electromagnetic interference Since the microwave induction module uses high-frequency microwave signals, it will cause interference to surrounding electronic products and affect other equipment. Please be careful not to place it too close to other electronic devices during use. to avoid interference. 3. Line installation needs to be done with caution Since the microwave sensor module has relatively high requirements on circuits, it requires experienced professionals to install it. If the circuit is not set correctly, false detection or false alarms may occur. 4. Higher cost The production of microwave sensor modules requires relatively advanced technology and cost, so the price is higher. If the same performance is compared, the price of microwave sensing modules is higher than that of infrared sensing modules. As a new high-tech sensing technology, microwave sensor module has many advantages, such as high reliability, high sensitivity, fast response, high flexibility, etc. It is an ideal choice for security monitoring and other fields. However, it also has its shortcomings, such as poor detection ability of small objects, large electromagnetic interference, careful line installation and high cost. Overall, microwave induction modules have more advantages than disadvantages, and as technology continues to advance, its disadvantages will gradually be improved. Therefore, when applying, we should choose the appropriate sensor module according to the actual situation to ensure that it works stably and reliably.
