Design and development of a low cost circuitry for Appliance Automation in educational institutions

Electrical energy consumption of a nation is an indicator of the economic and social growth of the country. Utilizing electricity efficiently and reducing its wastage as much as possible is an important criterion considering the depleting natural reserves of fossil fuel traditionally used for its generation. The ever increasing demand of electricity places its judicious and efficient use at a prime importance for its consumers. This paved the way for developing appliance based automation for energy conservation. In an educational institution like college or university that has comparatively large infrastructure, it is quite difficult to regulate appliances manually 24/7 throughout the year. In light of this, and to prevent the superfluous usage and consumption of electricity, this paper presents analysis, design and development of low cost, simple circuitry and low power consumption device to automatically regulate electrical appliances based on motion detection. Proteus 7 software platform has been used for circuit designing as the simulation tool, Dip trace has been used as the PCB designing tool, while MATLAB has been used for programming as well as a simulation tool.
