Control method of indoor environment using of ubiquitous smart system

PURPOSE: A ubiquitous smart indoor environment control method is provided to sustain accurate indoor temperatures and environments by analyzing accumulated data including the heart beat of a human body. CONSTITUTION: When a human is in an indoor area, a system grasps the location of the human by using a mobile sensor(S110,S120). The system measures the heart beat and brainwaves of the human by using the mobile sensor(S130). An indoor environment control unit of the system calculates a comfort index, the sensed temperature of the human, and the correlations between the heart beat and the brainwaves(S140). The indoor environment control unit controls the operation of a home appliance according to the sensed temperature and the comfort index(S150).
