Solar energy, LED based solar street lighting using microcontroller 8051 ; charging of battery controlled by charge controller circuit; measurement circuit senses 4 parameters
As we all know that energy consumption has increased a lot and sources of energy are limited so in order to meet the increasing demand of energy use of renewable sources of energy is a must Keeping this in mind in this paper we are discussing about SOLAR P0WERED LED STREET LIGHT WITH AUTO INTENSITY CONTROL. The project is designed for LED based street lights with an auto-intensity control that uses solar power from photovoltaic cells. A charge controller circuit is used to control the charging of the battery, and an LDR is used to sense the ambient light on day time.We have also attempted to measure the solar cell parameters through multiple sensor data acquisition. This street light is driven by solar energy and apart from this it also controls its intensity from dusk to dawn depending upon the brightness. In this system, different parameters of the solar panel like light intensity, voltage, current and temperature are monitored using a microcontroller of the PIC16F8 family.A case study is also done to show advantages of solar led street light compare to that of traditional street light.The intensity of street lights is re-quired to be kept high during the peak hours.This street light can save a large amount of electricity compared to the tradition one which are alight to their maximum intensity at all times after they are switched on.
