What is street light circuit?
Street light circuit. The circuit uses a Light Dependent Resistor (LDR) to sense the light . When there is light the resistance of LDR will be low. So the voltage drop across POT R2 will be high. This keeps the transistor Q1 ON. The collector of Q1(BC107) is coupled to base of Q2(SL100).
How do you make an automatic street light system?

How does automatic street light circuit works?
A high-intensity discharge lamp emits light by an arc of electricity created between two electrodes. The electrodes are in a transparent tube filled with gas and metal salts. The electrical arc generates heat, which works with the gas and metal to create light-emitting plasma.
How LDR is used in street lights?
Street lights are designed to switch on automatically when it is dark and switch off when there is light so as to save energy. A common device used is called a light dependent resistor (LDR). It is a resistor with resistance that changes according to the amount of light falling on it.
What are the advantages of automatic street light?
There are lower chances of the automatic street light system overheating & risk of accidents is also minimized. Cost of operating automatic solar street lights is far less when compared to the conventional street lights. The automatic street light system is eco-friendly & hence helps in reducing the carbon footprint.
Why is LDR used in street lights?
What is the circuit diagram of a street light?
Below is the circuit diagram of this Light sensing Street Light: In this project, we have used an LDR (Light Dependent Resistor) which is responsible for detecting light and darkness. The resistance of LDR increases in darkness and reduces in presence of light.
How does an automatic street light controller work?
There are several ways to turn on the street lights but the following circuit describes an Automatic Street Light Controller Circuit that uses LDR and Relay to perform this job automatically.
How is the LDR used in street lights?
Previously we have built many useful circuits using the LDR: Below is the circuit diagram of this Light sensing Street Light: In this project, we have used an LDR (Light Dependent Resistor) which is responsible for detecting light and darkness. The resistance of LDR increases in darkness and reduces in presence of light.
What kind of microcontroller is used for street lights?
To get an idea about the circuit built using microcontroller, read the post: Street Lights that Glow on Detecting Vehicle Movement. It is an Operational Amplifier IC. It is available ib 8-pin DIP Package and can be used in several configurations like Amplifier, oscillator, comparator etc.
