Automatic Street Light

Components:

PCB Board

LED

LDR

1×330 ohm resistor

1×220 k ohm resistor

1xBC548 transistor

9V Battery

9V Battery Holder

Tools:

PCB Drill

Cutter

Scissor

Soldering Iron, Wire and Paste

Black or white tape

Both side sticking tape

Step 3: Finalising

Dig holes on the PCB Board by the PCB Drill. Then solder all the components according to the diagram by the soldering iron. Finally stick the wires & the battery with tape. Hurrah! You have made it! 😀

Caution: Be careful while working with the soldering iron!

Conclusion:

My perspective is to make this prototype for saving energy. Usually Street Lights remain on till the morning, even till 10 a.m. also. It consumes a great amount of electricity. The technology will work as described above. When the Sun Will set, the lights will on and when the Sun will rise, the lights will off. By making the real mechanism of this prototype we can save a huge amount of electricity. Though it needs more Lab tests, more development as well as more perfection, it will be a revolutionary step towards the future technology!
