Street light automation project.

We are going to discuss here advantages disadvantages and applications of automatic street light and advantages are. 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. This project design is centered on solar energy as fast growing technology for street lighting with the use of a solar module. 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.

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. Or a ldr light depending resistor which eliminates human intervention for manual switching or control 1 4 significance of the study. 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. Download automatic street light ppt with pdf report.

The sensitiveness of the street light can also be adjusted. It automatically switches on lights when the sunlight goes below the visible region of our eyes. 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. In this project we are going to build an automatic street light which remains off in day light but turns on during night.

It automatically switches on lights when the sunlight goes below the visible region of our eyes. E g in evening after sunset. How to make an automatic street light project using ldr with arduino note. This automatic street light controller project is made using an ldr light dependent resistor with arduino.

Circuit of automatic street light 10. 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. The automatic control process of the light can be achieved by a photocell. Automatic street light using ldr.

The important considerations in the development of street light control systems are automation power consumption and cost effectiveness. Disadvantages it has a limitation of power light turns on when shadow falls on ldr led is a low voltage device 12. 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.

There s light and that s why street light is off.
