Part of the Electronics glossary: An accelerometer is a device that measures changes in gravitational acceleration in a device it may be installed in. Accelerometers are used to measure acceleration, tilt and vibration in numerous devices. At rest, an accelerometer measures 1g: the earthâs gravitational pull, which registers 9.81 meters per second or 32.185 feet per second. Accelerometers that use the piezoelectric effect measure a small voltage change. Others measure capactitance between two components.
