Simple Light Sensor Circuit Circuit Diagram

Simple Light Sensor Circuit Circuit Diagram Learn how to make a light sensor circuit using LDR, Darlington pair, relay, and other components. The circuit can automatically switch on and off electrical loads based on the daylight intensity. In the Light Sensor Circuit (first diagram) when the brightness of light increases, the LDR's resistance reduces and so the voltage at the base of transistor increases (because if LDR resistance reduces, the voltage drop(gap) across the LDR, towards positive side decreases). Once this voltage increases above the required threshold voltage at

The circuit shown in figure 1 is a very simple light sensor circuit that will activate an LED when the LDR in the circuit receives light. The circuit shown in figure 2 is using a relay at its output and when light falls on the LDR it will activate the relay Hello Readers, We frequently add new circuit diagrams, so do not forget to come back Learn about different types of light sensors, such as photocells, LDRs, photodiodes and phototransistors, and how they work. See circuit diagrams and examples of light sensor applications in electronics and photography.

The light sensor circuit is one of the coolest circuits in basic electronics projects. It detects the quantity of light present in the environment and the results can be detected by the brightness of the LED. This circuit may be useful for knowing the working of LDR (Light Dependent Resistor) or Photoresistor, the working of NPN Transistor, and

In this tutorial we'll learn how to make a light sensor circuit using LDR (Light Dependent Resistor), 555 timer IC and a few other electronics components. This circuit detects light incident on the LDR and turns on LED whenever the intensity of light is greater than a certain level. Circuit Diagram Instructions to Build This Circuit. Step
