AUTOMATIC NIGHT LIGHTS USING LDR

. . AUTOMATIC NIGHT LIGHTS USING LDR.

. . INTRODUCTION. Automation systems [1] are being preferred over the manual mode because it reduces the use of energy to saves energy. These automation systems play an essential role in making our daily life more comfortable and facilitate users from ceiling fans to washing machines and in otherapplications [2]. Among all exciting applications, street lights play a vital role in our environmentand also plays a critical role in providing light for safety during night- time travel. In this scenario,when the street lights are in working functionality over the whole night that consumes a lot of energy and reduces the lifetime of the electrical equipment such as electric bulb etc. Especially incities’ streetlights, it is a severe power consuming factor and also the most significant energy expenses for a city. In this regard, an intelligent lighting control system can decrease street lightingcosts up to 70% [3] and increase the durability of the equipment.
