Occupancy based lighting control technology and its application thereof

摘要

This disclosure relates to a method of detecting an occupancy state of a living space for controlling an on/off performance of an electrical apparatus. The method comprises using a motion sensor to send wave signal and detect wave signal reflected from a moving human body and using a dual sensitivity detection arrangement including a low sensitivity detection mode and a high sensitivity detection mode respectively performed for identifying the wave signal being a motion signal according to the electrical apparatus being in a turned-off state or in a turned-on state. The dual sensitivity detection arrangement enables the motion sensor to more precisely detect the occupancy state of a living space while minimizing a probability of the electrical apparatus being activated by a noise signal.
