Sensors
What are Sensors?
noun
a device which detects or measures a physical property and records, indicates, or otherwise responds to it.
"to ensure greater response and surer handling, the engineers used electronic sensors to monitor each wheel"
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.
