Automatic Street light circuit

Last Updated on November 27, 2024 by Admin Leave a Comment

The post explains a simple automatic street light circuit which switches ON at night and switches OFF at day time.

Circuit Explanation

The circuit chart show here is that of a road light that consequently switches ON when the sunsets and turns OFF when the sun climbs. Actually you can use this circuit for executing any sort of programmed night light.

The circuit utilizes a Light Dependent Resistor (LDR) to sense the light .When there is light the safety of LDR will be low. So the voltage drop crosswise over POT R2 will be high.This keeps the transistor Q1 ON. The gatherer of Q1(BC107) is coupled to base of Q2(SL100). So Q2 will be OFF thus do the transfer. The globule will stay OFF.

At the point when dusks the safety of LDR increments to make the voltage over the POT R2 to lessening underneath 0.6V. This makes transistor Q1 OFF which thus makes Q2 ON. The transfer will be stimulated and the lamp module will sparkle.

Notes.

POT R2 can be utilized to change the affectability of the circuit.

You can utilize globule of any wattage, if that transfer ought to have the sufficient rating.

The Automatic Street light circuit can be controlled from a managed 9V DC power supply.

The hand-off K1 can be a 9V SPDT transfer.

About Admin

Hey friends, Thanks a bunch for stopping by this site! I am an engineer with a Bachelor of Engineering in Electronics and Telecommunication. One of my passions is gathering information from all sorts of electronics books and tutorials. I then take that information and compile it into a language that is super easy to understand. My goal is to make those complex electronics circuit concepts and technical terms much more accessible for all the new and budding electronics engineers out there. I can also design customized circuit diagrams as required by the users.
If you have any questions related to this field, please do not hesitate to drop a comment! I am always here and ready to help you out with any queries you might have. I cannot wait to hear from you!
