SMART STREETLIGHT CONTROLLING SYSTEM WITH LDR AND IR SENSOR USING ARDUINO UNO

Abstract

Smart Street light is an automated system which automates the street. The main aim of Smart
Street light is to reduce the power consumption when there are no vehicle movements on the
road. The Smart Street light will glow with high intensity when there are vehicles on the road
otherwise the lights will have less brightness than when the lights are completely turned on.
This means when there is no vehicle around, the intensity of light will be around 30%. With
advancement of technology, things are becoming simpler and easier for everyone in the world
today. Automation is the use of control systems and information technologies to reduce the
need for human work in the production of goods and services. In the scope of industrialization,
automation is a step beyond mechanization, whereas mechanization provided human operators
with machinery to assist the users with the muscular requirements of work, automation greatly
decreases the need for human sensory and mental requirements as well. Automation plays an
increasingly important role in the world economy and in daily experience. Automatic systems
are being preferred over manual system. The research work shows automatic control of
streetlights as a result of which power is saved to an extent. The Smart Street light provides a
solution for energy saving which is achieved by sensing an approaching vehicle using the IR
sensors and then switching ON a block of street lights ahead of the vehicle with high intensity.
As the vehicle passes by, the trailing lights reduce its brightness. Thus, we save a lot of energy.
So, when there are no vehicles on the highway, then all the lights will reduce its brightness
intensity to 30%.
