AUTOMETIC STREET LIGHT CONTROLLERS

When darkness absorbs on LDR (Light Dependent Resistor), street lights LED glow and when brightness absorbs on LDR, then light does not glow. Due to this energy can be saved and no manpower required to operate street light. It is advance technology than Timer Sensor. In this project components like PCB, LDR (Light Dependant Resistor), 4.7k Ohm resistor, 1k ohm resistor relay in 4007 diode, 2 LED are used.
