## Overview

The 10pcs 5MM LDR Photosensitive Sensor Module is a compact and efficient light detection solution designed for seamless integration with microcontrollers like Arduino. With its ability to detect ambient light intensity changes, this module is perfect for creating automated light-operated switches and enhancing your DIY projects.

## Description

Features:1. A sensitive sensor type photoresistor2. The comparator output signal is clean, good waveform, driving ability, more than 15mA.3. Adjustable potentiometer to adjust the brightness of the light detection4. Working voltage: 3.3V-5V5. Output format: digital switching outputs (0 and 1)6. A fixed bolt holes for easy installation7. PCB size: 3.2cm x 1.4cm8. Wide voltage LM393 comparator instructions1.The photoresistor module is most sensitive to ambient light, generally used to detect the brightnessof the surrounding environment, triggering a single-chip or relay module;2. When the brightness of the ambient light reaches the set threshold, the DO end outputs a high level.When the ambient light brightness exceeds the set threshold, the DO end outputs a low level;3. The DO output terminal can be directly connected to the single-chip microcomputer, and the high-low levelis detected by the single-chip microcomputer, thereby detecting the change of the light brightness of the environment;4. The DO output terminal can directly drive the relay module of the store, which can form a light controlPackage：10* 5MM LDR Photosensitive Sensor Module

## Features

- the DO output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect the environment light intensity change;
- the DO output can be directly driven our relay module, which can form a light-operated switch.
- photosensitive resistance module's most sensitive to ambient light, commonly used to detect environment around the brightness of the light, or MCU trigger relay module, etc.;
- The module in the environment light intensity than set threshold, output high level DO end, when the environment light intensity more than set threshold, the DO output low level;
