Abstract:
Street lights pay a very important role for lightening the walkway during nights when surroundings go dark. It is also very important for the vehicles running during the night for the proper direction of the roads. Nowadays controlling the street lights require human presence to switch them ON/OFF which means this system is not digitalized yet. This human controlled system has the disadvantage of having regular individual presence to turn the lights ON/OFF which is a loss of electrical energy and manpower because this people can be deployed somewhere else. Thus to overcome these problems the controlling system might be converted to a system where it is controlled via wireless technology. In this paper, an automatic system is demonstrated to control the system by wireless technology using Arduino Uno. The system is programmed in such a way that the whole street light is divided in some sections which can be turned ON/OFF with a single short message service (SMS). The system can also be turned ON/OFF by using the intensity of light basing on day or nighttime and if intensity of light goes up or down a certain threshold value, the lights will be switched ON/OFF. The feature of getting the feedback about the functionality of the lights has also been added on this project. That means a feedback message will be sent via short message service (SMS) if the lights are not functioning properly. This automation process if utilized will save manpower, huge amount of electrical energy and make the system easier to control than the conventional controlling system.
