Iot based smart street light system.
Smart street lighting system project circuit diagram.
This project is about smart street light street light will turn on while vehicle is passing through it.
Please subscribeto my channel for more projects.
Circuit diagram and explanation.
The circuit employed here is an uncomplicated light dark activated switch and contains a relay at its output which simply turns on off a street light and further can be extended to control any electrical appliance in a household.
The resistance of ldr increases in darkness and reduces in presence of light.
It 39 d be very simple actually.
Project showcase by sagnik ghosh.
The expense spent on the street light can be used for other development of the nation currently a manual system is used where the light will be made to switched on off i e the light will be made to switch on in the evening and switched off in the morning.
Circuit diagram for this iot based smart street light is as follows.
This is an innovation of street lights to a greater level.
Automatic street lights turn themself on and off automatically by sensing intensity of light with the help of lights sensors.
Put the coil for a contactor that would switch the mains power for the street light on and off in series with the transistor.
When vehicle passes by a particular ir sensor it senses the position of vehicle and gives its signal to the arduino board and it will.
Control your light system using smart phone.
This is energy efficient circuit.
Here we are using 4 ir sensors that senses the position of the vehicle each ir sensor controls 3 led s.
Since ldr sensor generates variable resistance based on the amount of light falling.
Other automatic street lights are ldr based and lights up in darkness.
Smart street light circuit diagram and working.
It also counts the number of vehicles which can be used to.
Huge amount of energy is wasted at street lights as they are on all the evening and night.
The working of the project is explained here.
But this is totally different.
This circuit mainly consists esp8266 ldr sensor ir sensors and leds.
Here the ldr sensor is used to detect whether it is daytime or night time.
The cost spent is huge that all the sodium vapor lamps consume more power.
But in this project i have used ldr light dependent resistor.
There are many lights sensors available in market.
Below is the circuit diagram of this light sensing street light.
This circuit is same as a dark detector or light.
In this project we have used an ldr light dependent resistor which is responsible for detecting light and darkness.

Circuit diagram of automatic street light control is.
Below gif demonstrates the working of the project.
Now you can control your light system in your home using your smart phone by writing a character the led turn on or turn off.
The aim of this project is to design a street light control system using 8051 microcontroller which automatically turns on or off the street lights by detecting the movement of vehicles.
