data logger
(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.
