Transducer /Sensor is a detection device that can feel the information being measured, and can transform the felt information into an electrical signal or other required form of information output according to a certain law to meet the requirements of information transmission, processing, storage, display, recording and control.

The characteristics of the sensor include: miniaturization, digitalization, intelligence, multi-function, systematization and networking. It is the primary link to realize automatic detection and automatic control. The existence and development of sensors, so that the object has the sense of touch, taste and smell, so that the object slowly become alive. It is usually divided into ten categories according to its basic sensing function, such as thermal element, photosensor, gas sensor, force sensor, magnetic sensor, humidity sensor, sound sensor, radiation sensor, color sensor and taste sensor.
