Development of a home energy conservation system using power saving modes

Energy conservation has become more and more popular in recent years, both on the supply and demand sides. This is sponsored majorly by the rising price of energy production affecting both residential homes and industrial sectors. This project proposes a home energy conservation system using three different energy saving modes such as free, normal and extreme modes of operation. Energy was save based on mode of operation using different parameter as the limiting factors that include time, temperature and current respectively. The system comprises of temperature sensor, motion sensor, current sensor, real time clock, 4x4 keypad, LCD screen and an Arduino microcontroller. The Free mode makes use of time limiting factor to alter the time on and off of output, the Normal mode makes use of temperature sensor and motion sensor to regulate the outputs and the Extreme mode males use of current limiting capability to regulate outputs. The project was designed with the proteus software, while the programming was done on the Arduino IDE software. Result of this project shows the system can help conserve up to 45% energy depending on user’s preference.
