Simple Automatic Street Light Circuit Diagram. Thax a lot for sharing. There have been lot of problems in street lights.
Simple automatic street light circuit diagram. So the voltage drop across pot r2 will be high this keeps the transistor q1 on. Resistor 10kω 1.
This switching transistor collector terminal is connected with 9 volt relay terminal a 230 volt lamp is connected with relays common terminal and n o terminal.
This photoresistor circuit also can be used as an emergency light. This circuit is same as a dark detector or light detector circuit only here we have replaced simple led with a ac load using a relay. Circuit diagram of automatic street light. Circuit diagram of automatic street light controller switch circuit.
