FUNDAMENTALS OF COMPUTER

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: -The most common input devices are the keyboard, mouse, and touch screen. Portable keyboard, wireless mouse, and iPhone. There are hundreds of other input devices, like microphones to capture sound waves, scanners to capture image data, and virtual reality devices to capture our body movements.

Detailed explanation-3: -In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor.

Detailed explanation-4: -What is a sensor? 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-5: -Sensor Device is a type of input device which do some processing and generates output. The other meaning of sensor device is that it is a type of device which convert signals from one source of energy to the electrical domain. One of the sensor examples is a Light Dependent Resistor (LDR).
