How to Make a Small LED light Distance Sensor System Circuit Diagram 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 the impact of the sensitivity of the resistor on Build a DIY light sensor circuit with a PNP transistor. Simple guide to make an LED light up in the dark, complete with steps and practical tips.
We are going to build a simple Light Sensing circuit or Light Detector using LDR - a resistive light sensor, to control the ON-OFF of the system associated with respect to the intensity of light that falls on it. In this tutorial I'm going to show you how to build a really simple, light sensor, this uses an LDR. What is an LDR A Light Dependent Resistor (LDR) is a device whose resistance decrease with the respect to the light incident on it, it is also called photo-resistor. This project can be used to detect whether it is day or night depending on the light intensity, you may need an arduino to make A light sensor circuit activates when light is detected by the circuit. It is a simple circuit including a photoresistor followed by a transistor. When light strikes the surface of the photoresistor, light energy is converted into an electrical signal and thus, the circuit is operational.
