How To Make Automatic Day-Night Light Using LDR & Transistor By Technoesolution | #electronicsprojects
Description
Hello, friends welcome to "TECHNO-E-SOLUTION".Now we are going to make Automatic Night Light. If you want to make your outdoor light automatic follow this blog. I'm using LEDs as a lamp source for demonstration purposes you can replace the outdoor lamp, the Streetlamp that would you want to ON as dark night comes. In this project, you can simply connect any lamp across the relay which you want to automatically operate when night comes. In this project I used a 9V battery for supply and LDR are used for light detection purpose, But you can connect a solar plate/adapter to supply the circuit.
Working:-
Now see the circuit diagram there are LDR used for light detection as night comes the resistance of LDR get increases and the transistor gets off which turns ON the lamp connect across the relay. The variable pot is used to control the base current of the transistor hence you can adjust the circuit operation as per your requirements. Its working is simple to understand.
Material Required:-
Circuit Diagram:-
Note:- If you want to make PCB of this project you should need to print the above file with Setting (Actual Size> Print) otherwise PCB layout gets a wrong sized print. Print the Layout on glossy paper with size A4.
Take care while printing you should print this layout on a laser printer(Tonner powder) that doesn't print with a laser printer(INK).
