A sensor is a detection device, a tool for acquiring information, or a machine that transmits sensations. In its broadest definition, a sensor is a device, module, or subsystem commonly used in automatic control and measurement systems.

A sensor can be defined as a device or instrument capable of converting a measured physical quantity (such as speed, temperature, sound, light, etc.) into another physical quantity (usually electrical) that is easier to transmit and process. Commonly referred to as a probe, a sensor may also be known as a transducer, converter, transmitter, or detector.
