What is a sensor？

A sensor is a device, module or subsystem. Sensors detect events or changes in the environment and send information to other electronic devices, usually computer processors, used in manufacturing and machinery, aircraft and aerospace, automotive, medicine, robotics and many other aspects of everyday life. The application of sensors has gone beyond the traditional temperature, pressure or flow measurement fields, such as XIDIBEI sensors, and more and more sensors are manufactured into miniature sensors through MEMS technology.
