Abstract
Many city and municipal councils are facing challenges of high electricity bills for the street
lights as the demand for the security light has gone up. Coming up with an automatic street
lights is the only way to solve the challenges of high electricity bills for the councils. Also
there should be a proper monitoring of the street lights. The intensity of light is usually kept
highest when it is very dark and the intensity of light continue to decrease as the amount of
lightness continue decreasing until it shut downs when it is very clear in the morning. The
lights usually turns on and the intensity of the light continue to increase as the amount of
darkness increases.

HOW TO DESIGN AN AUTOMATIC STREET LIGHT CONTROLLER CIRCUIT
WITH GSM DEVICE USING RELAY AND LDR.
1.0 Introduction
Majority of the city and municipal councils around the world are facing challenges of high
electricity bills for the street lights as the demand for the security light has gone up. The
increase in the amount of the electricity bills has been attributed the early switching on and
late switching off of the street lights. Also poor monitoring of the street light has also been
attributed to be increasing the amount of electricity bills which the councils are paying.
Coming up with an automatic street lights is the only way to solve the challenges of high
electricity bills for the councils. Also there should be a proper monitoring of the street lights.
Updated information about the street lights needs to be submitted to the control centre of the
street light so as to ensure that there is proper monitoring of the street lights. Having the
updated information of the street lights in place it gives the maintenance team an easy time to
locate where the problems are in the system once they occur. The best way to achieve
automatic lighting for the streets is by having an automatic lighting system in place which is
able to relay messages when the lights are to go on and when they go off (Bedford, 2014, p.
346).
2.0 Aims/objectives of the project.
The objectives of this project are as stated below.
To find out the difficulties involved in street lighting.
To come up with a solution which will help in reduction of the electricity consumption.
To develop an automatic lighting system for the street light which uses light depended
resistors and the GSM network to relay messages to the control system.
