Automatic Street Light and Irrigation Enabled Smart Micro Ecosystem using Solar Energy
Abstract
Rapid growth in energy demand world widely, expensive and limited fossil fuels, and with new inventions and applications in the field of renewable energy sources; these all major points leads us to effectively use renewable energy sources with respect to green energy, less carbon foot print and safe future. This paper consist an effective smart micro ecosystem, for that an experimental setup has been conducted which includes two applications of renewable energy i.e. Automatic Street Light and Irrigation Control System using solar PV Module. In this paper firstly, Automatic Street Light Control System application has been shown where, timer IC 555 is used as a comparator which receive signal from LDR and act as a switch to turn ON and OFF street light automatically whenever the sunlight goes below the visible region and vice versa respectively. Secondly, for optimum gains on irrigation all kinds of advanced techniques are now being used to achieve high production rate which includes effective use of water resources. For that Irrigation Control System has been made to create an automated irrigation mechanism which turns the pumping motor ON and OFF on detecting the dry or wet soil moisture content of the earth respectively eliminating monitoring of water level in soil. LM324 comparator is used for comparing reference and soil condition parameters, which enables a pump controlled by relay using driver circuit. In this experimental setup mainly the solar power is used to supply required power to the pump and street lights. The main objective of this micro ecosystem is to save energy and maximum utilization of available energy smartly.References (22)
