摘要： Street Lighting is one of the most important and biggest energy consuming departments of the nation. On top of that, the most difficult thing is maintaining them. Consider a situation wherein the streetlight of a locality has stopped working. Now, the people of that area have to call and complain about the same and wait for days to get it repaired, leaving that area dark and socially unsafe. The proposed system consists of a Fault Detection Circuit using two photo sensors in addition with Arduino Uno microcontroller and GSM module [1], which automatically detects the fault in the streetlight. This eliminates manual complaining of the faulty streetlight and initiates sudden repair of the streetlight by the technician, which is being informed by Fault Detection Circuit via text message. Automatic turn ON and turn OFF feature has also been included using two photo sensors which turns ON the streetlight during dark hours and automatically turns OFF the streetlight during light hours. In addition to that, solar panels have been used as source for the streetlight and LED lights have been used for the emission of light, reducing the cost of electricity by 80%.
