ASL. Light

1.1 Problem Statement

Street lights among roads in our county have a high rate of power consumption which has led to incurring extra costs. This is due to often having the street lamps at maximum lighting throughout the entire night and also using high-intensity discharge (HID) lights which consume a lot of power. This leads to power wastage as there are times at night where there is zero to no activity and the lamps are at maximum brightness. A lot of time is also spent when fixing street lights. This is because it is often difficult for electrical technicians to easily identify malfunctioned lamps and often end up spending a lot of time searching for malfunctioned lamps. Traffic on major roads in the county still proves to be a major issue. This includes traffic load i.e. the number of vehicles per road. From the problems stated above, it has become important to develop a new thorough system that will be cost-effective, power-saving and aid in traffic management.

1.2 Objectives

i. To automatically turn on street lamps as day approaches and turn off as night approaches by use of light-dependent resistor.

ii. To use LED lights to provide the ability to optimize street lighting according to ambient lighting. Ambient lighting refers to providing sufficient light that ensures visibility and security within an area.

iii. To send notifications from lighting equipment about system status in order to improve the efficiency and effective of lighting maintenance resources.

iv. To gather data about the roads and to integrate this data within a wider systematic model.

v. To dim light to a lower consumption rate when there is zero on no road activity and increase it gradually to maximum lighting when there is road activity during night hours.
