Light Dependent Resistor and Its Applications

So, the LED does not light. However, when the light intensity onto the LDR is high, then the resistance of the LDR is low.So current flows onto the base of the first transistor and then the second transistor.Consequently the LED lights.Here, a preset resistor is used to turn up or down to increase or decrease the resistance.

How an LDR (Light Dependent Resistor) Works - Kitronik

What is an LDR (Light Dependent Resistor)? An LDR is a component that has a (variable) resistance that changes with the light intensity that falls upon it. This allows them to be used in light sensing circuits.

Solar street light - Wikipedia

Solar street lights are raised light sources which are powered by solar panels generally mounted on the lighting structure or integrated in the pole itself. The solar panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night.

light sensor and street light control using Arduino

Light sensor and street light control using Arduino is designed to measure the intensity of light or amount of light. Street light is controlled automatically with the help of the intensity of light and Arduino. Arduino UNO R3 is used in this project. Light-dependent resistor is used for the detection of light.

LDR Circuit Diagram - Build Electronic Circuits

The LDR circuit diagram works like this: When it's dark, the LDR has high resistance. This makes the voltage at the base of the transistor too low to turn the transistor ON. Therefore, no current will go from the collector to the emitter of the transistor. All the current will instead pass through the LDR and the potentiometer. When it's ...
