Below is the circuit diagram of this Light sensing Street Light project. 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. WebStep 3: Circuit Diagram Step 4: During Presence of Light When there is Light during day time then LDR resistance decreases. This makes voltage at base less than 0.6V and so, transistor moves in Cut-off mode – no current flows from Collector to Emitter acting as open switch. Step 5: During Absence of Light
