This is a light controlled led light circuit light activated switch which fully depends on light. The relay on. This makes the voltage at the base of the transistor too low to turn the transistor on. When it s dark the ldr has high resistance. You can use this for automatic light switch for street light. All the current will instead pass through the ldr and the potentiometer. The ldr circuit diagram works like this. Therefore no current will go from the collector to the emitter of the transistor. In this circuit 25 high bright. Ldr is used in this for sensing the dark and light.

By this light activated switch in day light will automatically switched off and at night switch on light.

Ldr circuit diagram dark sensor circuit. This is a light controlled led light circuit light activated switch which fully depends on light. In this circuit 25 high bright. Ldr is a light dependent resistor which resistance increases as darkness and its resistance is decreases when light falling on it. Ldrs or light dependent resistors are very useful especially in light dark sensor circuits. Ldr is used in this for sensing the dark and light. Normally the resistance of an ldr is very high sometimes as high as 1000 000 ohms but when they are illuminated with light resistance drops dramatically. This makes the voltage at the base of the transistor too low to turn the transistor on.
