## Overview

The Teyleten Robot 5MM LDR Photosensitive Sensor Module is a compact, highly sensitive light detection device featuring a digital output driven by an LM393 comparator. Operating between 3.3V and 5V, it offers adjustable brightness thresholds and a robust 15mA output capable of directly interfacing with microcontrollers and relay modules. Designed for easy installation and reliable performance across a wide temperature range, this 10-pack sensor set is ideal for smart lighting, environmental monitoring, and innovative Arduino projects.

## Description

About us: Sensor performance and features: 1.Using sensitive photoresistor sensor. 2. Comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA. 3.With adjustable potentiometer can adjust the detection light brightness 4 Working voltage 3.3V-5V 5.Output form: digital switch output (0 and 1) 6. With fixed bolt holes for easy installation 7 Small board PCB size: 32mm/1.26’’ x 14mm/0.55’’ 8.Using a wide voltage LM393 comparator 9.Working temperature: -20 ° C ~ +55 ° C 10.Product weight: 3.5g 11.Application: Light intensity detection, intelligent car light module, with directional, only sense light source in front of the sensor, better to use for searching light. Package including: 10 x sensor module Module instructions 1.The photoresistor module is most sensitive to ambient light, generally used to detect the brightness of 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 level is 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 control switch.

Review: Works for the Arduino - Great. Everything for the Arduino on desertcart!😁😄
Review: Compatible with 3.3v GPIO - Works well and consistently, and the sensitivity adjustment is easy to set. The output will go low when it sees light, as high as Vcc when it senses dark. If you supply 5v, it will output 5v. The output seems to have a high output impedance, so using a simple voltage divider resistor network to bring the output down to 3.3v is a bit problematic if using anything under 100k ohm resistors. Just measure the output to make sure. However, if you supply 3.3v for the Vcc, the output will go to 3.3v, which is compatible with most GPIOs (like the RP2040 uC). So no need for any kind of level shifting or voltage divider resistors. It uses VERY little current, so can be supplied by the 3.3v output of many uC boards.

## Features

- 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.;
- 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;
- 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.
