## Overview

The TCRT5000 Infrared Signal Reflective Track Sensor is a compact, versatile module designed for precise obstacle and line detection in robotics and smart devices. Operating within a 3.3V-5V range, it detects reflections from 1mm to 25mm and features a potentiometer for sensitivity adjustment. Its clean digital output and easy bolt-hole installation make it ideal for professional-grade robotic arms, smart cars, and automation projects.

## Description

Introduction: When the Indicator diode is lighted: That mean the target is beyonded the range of the detection.and the The infrared light can be reflected back ,the intensity is power enough, the infrared receiving tube is saturated, and the output of the module is Low level. However the Indicator diode is off: Which mean the infrared light can not be reflected back ,the intensity isn't power enough.The infrared receiving tube is in the off , at the same time, the output of the module is high level.Specification: 2.Working voltage 3.3V-5V 3.Detection of reflection distance: 1mm ~ 25mm 4.The comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA 5.Output form: digital switch output (0 and 1) 6.Using a wide voltage LM393 comparator 7.With fixed bolt holes for easy installation 8.With potentiometer adjustment sensitivity 9.Using TCRT5000 infrared reflection sensorPackage Included: 10pcs TCRT5000 Infrared Reflective IR Sensor Module

## Features

- Wide Application:For obstacle detection,Watt meter pulse data sampling,Detecting black and white line ,Detecting Fax machine and shredder paper,for limits of movement on robotic arm

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked great in my candy dispenser.
*by O***E on November 16, 2020*

I made a touchless candy dispenser for the pandemic. I used 3 of these sensors. One would start the machine when a hand was waved under it and two were used to sense if the candy dropped out. All three worked perfectly. It is important to note that the range of these sensors isn't very far, but for me that was fine. The sensitivity adjustment potentiometer worked fine as well.I know some people have had issues with not all of them working, but I don't see any reason to lower the stars since everything worked as expected for me. If I have a problem with any of the remaining 7 sensors, I'll update this review.These sensors were used with an Arduino Nano.

### ⭐⭐⭐⭐ They work, for the most part
*by A***D on December 20, 2019*

Out of the 10, 2 of them were defective since none of the LEDs would glow and no data was being outputted to the digital or analog outputs. They should be tested before being implemented into a project. Despite this, the sensors worked well in my project, and having both an analog and digital output is a huge plus. The digital output can be easily adjusted with the potentiometer on the board.

### ⭐⭐⭐⭐⭐ Good sensor
*by E***E on December 12, 2019*

The sensors were great and it came on time as well. I was able to finish my project.
