A sensor is a device that detects and responds to some input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or anyone of a significant number of other environmental phenomena. The output is generally a signal that is converted to a human-readable display at the sensor location or transmitted electronically over a network for reading or further processing.
