Abstract: A digital displacement sensor and a displacement measuring method thereof, pertaining to the technical field of displacement sensors. The digital displacement sensor includes a housing and a circuit board, and the circuit board is arranged inside the housing. The housing is provided with a window and an opening. The circuit board is provided with a signal acquisition module, an analog front end circuit, a digital compensation circuit, and a signal output interface. The digital displacement sensor allows to alternatively fix the sensor or measured object according to the structure. The measurement can be performed as long as a relative movement between the sensor and the measured object occurs. Factors such as material of the measured object etc. are not limited, so materials such as steel belts, aluminum plates, plastics etc. can be flexibly used. Merely surfaces of the measured object need to be coated with corresponding stripes.
