Intelligent Control of Electrical Power Consumption and Wastage in University of Benin Lecture Theatres
Abstract
This paper investigates electrical power consumptions and wastages in
lecture theatres (LTs), drawing offices (DOs) and laboratories of the
University of Benin, Benin City, Nigeria. It identifies one major source
of electrical energy wastage; lightings and fans in the lecture theatres and
laboratories remaining on in the absence of students, technicians,
technologists and lecturers. The aim of this work is to design an
intelligent system to control the lightings and fans in the lecture theatres
and laboratories, analyse the amount of electrical energy consumed with
and without the intelligent system and calculate the energy wastage. The
system turns on lightings and fans within the section in the LT where
there are persons while lightings and fans in other areas remain turned
off. The intelligent system was designed using PIC16F877A
microcontroller, Passive Infra-Red (PIR) motion sensors, relays, energy
saving bulbs and the code was written using MicroC Pro.
