data logging

(data)

(data acquisition) Storing a series of measurements over time, usually from a sensor that converts a physical quantity such as temperature, pressure, relative humidity, light, resistance, current, power, speed, vibration into a voltage that is then converted by a digital to analog converter (DAC) into a binary number. Data logging hardware may have several DACs for multiple simultaneous measurements. The hardware usually connects to a parallel port, serial port or USB port on a PC.
