Abstract

The present invention relates to a motion sensor and method of operating the motion sensor, which can adjust the range of a detection area. For this, the motion sensor according to the present invention includes a detection unit for outputting a variation signal corresponding to motion. A threshold level setting unit variably sets at least one changeable threshold level. A comparison unit detects the motion by performing a comparison operation based on the changeable threshold level and the variation signal at threshold sensitivity corresponding to the changeable threshold level.
