Principles and advantages of radio frequency sensors.Infrared sensing module

　　The working principle of the radio frequency sensor is a sensor developed by using the characteristics of radio frequency. The probe can not only receive radio frequency, but also transmit radio frequency. Its principle is a sensor that converts radio frequency signals into other energy signals. It has the characteristics of high frequency, good directionality, and directional propagation. It has strong penetrating ability to solids and liquids. Therefore, it is widely used in industry and medicine.

　　Radio frequency sensors are also very common in life, just like bats flying at night. They use radio frequency to determine whether there are obstacles on the route ahead. Based on their characteristics, reversing radars and automatic avoidance systems for robots have been developed. Its strong anti-interference ability to the environment is the main reason why it is favored by various fields. What are its advantages?

　　Radio frequency sensors are different from other types of sensors in that they can continue to detect in a dark environment without light, are not affected by the environment, and can adapt to a wider range of environments than other types of sensors. And it has no requirements for the color and material of the object to be measured. No matter where it is, what color it can be accurately measured without any error. At the same time, it can perform very well in environments with dirt or high humidity. Unlike other types of sensors, RF sensors can perform as well even under conditions of accumulation of water or dust and soil. Accurate and error-free measurement. And compared to other sensors in measuring thickness and distance, the accuracy is much more accurate. Its high sensitivity and strong penetrating power enable it to better detect external and even internal objects to be tested.

　　But it also has some shortcomings. Because of its radio frequency characteristics, it can no longer work in a vacuum environment, and it will also affect the accuracy of its work under water. Therefore, when the customer uses it, he should pay attention to the use of the radio frequency sensor in an environment where the medium is helping to transmit it.
