Using Motion Sensor for Auto Controlling Air Conditioner’s Temperature

Abstract

Article discusses the system of automatic air conditioning temperature setting using human motion detection with PIR sensor. Automatic temperature setting process begins when the absence of humans in a room and the system began to increase the waiting time until the time determined in accordance with the mode selected by the user. Having arrived at the specified time then the system will output a temperature rise of 1-4 ˚ C. If there is detection of PIR sensors after the system issued an order form of the temperature rise of 1-4 ° C then the system will issue an order decreasing the temperature of 1-4 ° C. The experimental results showed that the system can work well in the area of the room 3x3x3 cubic meter. (Abstract) Keywords- Controller, AC’s temperature, motion sensors, human presence.
