Sensors can help you detect events or changes in their environment and send this information to other electronics. In applications over a wide range of industries sensors are a key enabler for automation of production processes. In analog or digital signals, they will provide you with important information on a physical presence, physical properties, motion or proximity of objects. You need them to test, measure, and control various processes and machine functions. With the advent of the Internet of Things (IoT), the need for sensors functioning as primary data generators is increasing.
