Street Light Automation Project

Or a ldr light depending resistor which eliminates human intervention for manual switching or control 1 4 significance of the study.

Street light automation project.

We are going to discuss here advantages disadvantages and applications of automatic street light and advantages are. Automatic street light using ldr. The automatic control process of the light can be achieved by a photocell. Now let s have a look at its on state in the below figure.

Now let s have a look at the off state of this automatic street light project shown in below figure. This project design is centered on solar energy as fast growing technology for street lighting with the use of a solar module. It automatically switches on lights when the sunlight goes below the visible region of our eyes. By using this system manual works are removed.

E g in evening after sunset. Download automatic street light ppt with pdf report. It is a simple and powerful concept which uses transistor bc 547 npn as a switch to switch on and off the street light system automatically. Disadvantages it has a limitation of power light turns on when shadow falls on ldr led is a low voltage device 12.

In our project we have used four l e d as a symbol of street lamp but for high power switching one can connect relay electromagnetic switch at the output of pin 3 of i c 555 that will make easy to turn on off any electrical appliances that are connected through relay. Photo resistors change light into electricity and are not dependent on any other force ldrs are delicate inexpensive and readily obtainable devices they are small enough suitable into virtually any electronic device and. Circuit of automatic street light 10. The sensitiveness of the street light can also be adjusted.

In this project we are going to develop a project called street light control using 8051 microcontroller in which the street lights are automatically turned on or off based on the movement of the vehicles. How to make an automatic street light project using ldr with arduino note. In this project we are going to build an automatic street light which remains off in day light but turns on during night. Advantages energy savings low cost safety and security automated operation 11.

It automatically switches on lights when the sunlight goes below the visible region of our eyes. There s light and that s why street light is off. Automatic street light control system is a simple and powerful concept which uses transistor as a switch to switch on and off the street light automatically. Save electricity by this simple project it glows during night and switches off automatically as the sun rises i have tried a lot of circuits but i made one and this works perfectly it is a project depicting the proverb try and try till you succeed.

You can see in the above figure that the ldr is detecting the light but the lamp is off so its like a day time.
