DESIGN AND DEVELOPMENT OF A SMART LIGHTING POINT AND TEMPERATURE CONTROL SYSTEM

Abstract

Conservation of energy which is the main focus of this paper is very important in order to reduce utility cost in residential buildings. Hence, a Smart lighting Point and Temperature Control system is designed and developed to control automatically, the electrical appliances in residential buildings. Smart lighting Point and Temperature Control system consist of a microcontroller, which serves as the brainbox of the system. The functionality of a Passive Infra-red sensor is employed in this system to detect the motion of a person entering or leaving the building; the system further detect the difference in surrounding light intensities through the aid of a Light Dependant Resistor to turn ON/OFF the lights automatically. it then checks to see if the temperature within the building is above the pre-set value to turn ON/OFF the cooling system. The number of persons entering or leaving the building is displayed on a seven-segment display
