(hardware)

sensor - An electronic device used to measure a physical quantity such as temperature, pressure or loudness and convert it into an electronic signal of some kind (e.g a voltage). Sensors are normally components of some larger electronic system such as a computer control and/or measurement system. Analog sensors most often produce a voltage proportional to the measured quantity. The signal must be converted to digital form with a ADC before the CPU can process it. Digital sensors most often use serial communication such as EIA-232 to return information directly to the controller or computer through a serial port.

detector, device, electric eye, feel, magic eye, metal detector, mine detector, photocell, photoconductive cell, photoelectric cell, sense, sensing element, trace detector
