In order to sense a physical phenomenon, the sensor creates an output signal

A sensor is a device that detects and responds to physical input. Light, heat, motion, moisture, pressure, or any other environmental phenomenon can be used as input. The output is typically a signal that is converted to a human-readable display at the sensor location or electronically transmitted over a network for reading or further processing.

Sensor are crucial in the internet of things (IoT). They enable the creation of an ecosystem for collecting and processing data about a specific environment, allowing it to be monitored, managed, and controlled more easily and efficiently. IoT sensors are used in homes, in the field, in automobiles, on aeroplanes, in industrial settings, and in other settings.
