Here I have made a prototype of automatic street light. When Darkness will appear on it, LED will glow automatically & when light will appear on it, LED will off automatically. You can also make this by following some easy steps.
Step 1: Understanding circuit diagram
Here is the circuit diagram of automatic street light. This is a very easy diagram. Just follow it. You will also be able to make one.
NOTE: This is a standard circuit diagram. If you are following this diagram, you may need extra wires. I have followed same diagram but made different structure, as a result it didn’t take extra wires. So choose the structure wisely!
Step 2: Gathering Ingredients
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!
