Sensors are complex devices that are often used to detect and respond to electrical or optical signals. Sensors convert physical parameters (such as temperature, blood pressure, humidity, speed, etc.) into signals that can be measured electrically. Proximity sensors detect the presence of objects with almost no point of contact. Due to the lack of contact between the sensor and the object under test and the lack of mechanical parts, these sensors have long service life and high reliability. The proximity sensor emits an electromagnetic or electrostatic field or electromagnetic radiation beam (such as infrared) and waits for a return signal or change in the field. The object to be sensed is called the target of the proximity sensor.
