Nice Automatic Street Light Control Circuit Diagram
Circuit diagram of automatic street light controller switch circuit.
Automatic street light control circuit diagram. In fact you can this circuit for implementing any type of automatic night light. Components used in this circuit. 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.
Resistor is not polarity sensitive. Automatic street light control system sensor using ldr transistor bc 547 very simple. 12 volt battery is used to power this circuit diagram.
First start form battery. Transistors are used as a switch. This circuit can also be built using microcontroller.
Moreover the output is just of 5v but the street lights are of normally 220v ac or 12v dc. When intensity of lights falls below minimum level. Potentiometer 10kω 1.
The collector of q1 bc107 is coupled to base of q2 sl100. Automatic street light control. We have tried this one in this tutorial but you can also try the second one mentioned below.
Three light emitting diodes are used this project. After that there is led is connected with 330 ω resistor but be care full the light emitting diode. Let try to understand this circuit.
