SENSOR UND sensor, also known as a displacement sensor, is a type of sensor used to detect the distance to an object to perform a preset function, and has been widely applied. Main products include mobile phone proximity sensors and long-distance measurement sensors, which are used in smart belts. Proximity sensors can be classified into optical proximity sensors, infrared proximity sensors, ultrasonic proximity sensors, and others based on their working principles. Most proximity sensors used in mobile phones are infrared proximity sensors, which have an infrared emitting tube and an infrared
