It is the device which provides input to a main control system (like a Processor or a Microcontroller). It can also defined as a device that converts signals from one energy domain to electrical domain.

Detailed explanation-5: -A good example of a sensor is a motion sensor that connects to a computer to help detect motion within a building. Other sensors may detect temperature, light, moisture, pressure, radiation, and sound.
