Automatic Street Light Controller Circuit Using Relays and LDR

Description. The circuit diagram present here is that of a street light that automatically switches ON when the night falls and turns OFF when the sun rises.In fact you can this circuit for implementing any type of automatic night light. The circuit uses a Light Dependent Resistor (LDR) to sense the light .When there is light the resistance of LDR will be low.

Automatic Street Light Control System using LDR ...

Circuit Diagram 2 . Automatic Street Light Control System.(Sensor using LDR & Transistor BC 547.) Very Simple. As Light is falling on LDR ( Light Dependent resistor) So LED does not glow. ( LED = Off). You can see now that we have blocked light falling on Light dependent resistor(LDR), so …
