IMPROVING ENERGY EFFICIENCY USING MICROCONTROLLER BASED EMBEDDED SYSTEMS

Abstract

Energy efficiency refers to the efforts made to reduce the energy consumption of a system through installation of or replacement with more efficient end-use devices or more effective operation of existing devices, while having it perform the same functions. First chapter of this thesis presents Introductory Concepts of Energy efficiency and the universal call for sustainable development. The problem definition of the research is the challenge caused by increased electricity demand and the increase of greenhouse gas emissions. Leading us to three main objectives: 1) saving consumed energy at home, 2) review home solutions to improve energy efficiency, 3) Implementation of a prototype model of home automation lighting system to detect occupants and sense light. The used methodology in this work is a qualitative strategy of design reliable microcontroller based embedded system which is a simple prototype of lighting control automation system to test the concept and the main functional capabilities of the proposed objectives. The system framework consists of microcontroller, sensors, relays and other components chosen and designed to develop a PCB board which testing the software program on the microcontroller chip. The code written is described with registers associated parameters to act within targeted scenario.
