Detailed explanation-1: -Sensor is an input device which provides an output (signal) with respect to a specific physical quantity (input). 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-2: -A sensor is a device that detects and responds to some type of input from the physical environment. The input can be light, heat, motion, moisture, pressure or any number of other environmental phenomena.
Detailed explanation-3: -A physical sensor is a device that measures a physical quantity (like temperature) and converts it into a signal which can be read by an observer or by an instrument.
Detailed explanation-4: -A sensor is a device that measures physical input from its environment and converts it into data that can be interpreted by either a human or a machine. Most sensors are electronic (the data is converted into electronic data), but some are more simple, such as a glass thermometer, which presents visual data.
