Simple Automatic Street Light Circuit Diagram with LDR

So to flow current we have to apply have current on base for flow current, so we off the light. Resistance of LDR is low current will flow it and apply on base. When current is passes from base current will also flow have transistor then passes form led. LED is on, again when you on the light led off. Dome Video of automatic street light:

Dark/Light sensor using transistor | BuildCircuit - Electronics

Automatic dark detector senses darkness. As the light level decreases and LDR meets the maximum threshold resistance, the circuit automatically switches on the LED D1. Dark sensor with variable resistor: A dark detector can be made using a variable resistor. The sensitivity of the circuit can be adjusted with a variable resistor.
