About this document

Light Activated Switch Circuit Design by Manoj Kumar Thadigoppula Netha is a document available to read on EtoBox.

This document describes a light activated switch circuit that uses a light dependent resistor (LDR) and comparator IC LM311. The circuit works by comparing the voltage across the LDR to a reference voltage, with the output switching the transistor and relay depending on whether the LDR resistance is high or low based on light intensity. The potentiometer R1 can be adjusted to set the desired light intensity threshold for switching the relay on or off. When assembled on a PCB, the circuit provides a simple l
