Ldr Automatic Street Light Circuit Diagram. We have tried this one in this tutorial but you can also try the second one mentioned below. Here two bc547 npn transistors are used to operate the relay.
When we say automatic night light circuit we may think about the nightlight street illumination system that automatically turns on at night and they turn off in the daytime all this automation process is possible with an electronic circuit that has a sensor that detects the sun intensity we will replicate this process but very simple with the help of a light depending resistor that has the. We have tried this one in this tutorial but you can also try the second one mentioned below. Working of automatic street light controller switch circuit.
It has a resistance of almost 1 mega ohm when it is in total darkness but its resistance is about 5k ohms when exposed to full brightness.
Automatic street light control system sensor using ldr transistor bc 547 very simple. Here two bc547 npn transistors are used to operate the relay. Ldr light depending resistor whose resistance is based upon the quantity of the light declining on it along with a few more components. We have tried this one in this tutorial but you can also try the second one mentioned below.
