This analog Line sensor array for line follower robots is based on TCRT-5000 IR sensors and have been designed for Arduino Mega users. It has a total of 10 IR sensors and requires 10 analog pins of a microcontroller or Arduino board (like Arduino Mega).

If you are an Arduino Uno user, you can check out the 6 sensor variant of this sensor array. (click here)


This sensor has got IR LED control option that lets you turn ON and OFF the IR LEDs of the sensor array using a digital pin of Arduino. That ensures unnecessary power consumption when the sensors are not in use. Moreover, the ability to read IR sensors while turning ON and OFF the IR LEDs helps to eliminate effect of flash lights and sunlight.

 

This sensor array is similar to Pololu QTR sensors and fully compatible with Pololu QTR library. (click here)

 

Check Documents Tab for user manual.

 

Features:

1. Best analog line sensor for Arduino Mega. Also compatible with any 5V Arduino board.

2. Supports Pololu QTR library (QTR RA). You can use it just like a Pololu QTR analog sensor.

3. Sunlight and flash resistant. Ability to turn ON & OFF IR LEDs by arduino digital pin.

4. Small and compact design. Uniform 1cm distance between IR sensors for better line detection.

  • 1 cm spacing between two adjacent sensors, covering 9cm distance by the entire sensor array.
  • Recommended operational height from ground 3mm-15mm. (height of IR sensors tip, not the PCB).
  • Generates high voltage for white surface and low voltage for black surface on signal pins.
  • Large value difference for white and black surface at recommended operational height from ground (more than 3volts).
  • Recommended to use with arduino mega and other MCUs having at least 10 ADC pins

Q: Can it be used with vcc of 3.3v? If yes then will the output ever cross the limit of 3.3v? I will use it with a 32bit MCU which runs at 3.3v. Please reply urgently. Questioned by Anindya11, 31-Aug-2017

It will run in 3.3V but the sensor reading will be less. Answered by A.R, 07-Sep-2017 17:21 PM

Q: Tried this module for a PID based LFR with QTR library from pololu and it works with a little modification in the example code. Here's the interfacing code if it helps anyone. https://github.com/ahmadSum1/LFR/blob/master/IRArray_interfacing/Analogue/QTRLibrary_GenericAnalogArray_techshopBD/QTRLibrary_GenericAnalogArray_techshopBD.ino Questioned by saaakib, 15-Oct-2018

sir, can u tell me, if i use digital ir sensor tcrt5000 what kind of modification I have to do it?? Answered by Shikor, 20-Dec-2018 02:19 AM

Q: i need 1.5 cm line space and array-7. can you do that? Questioned by zhrony.bd, 08-Feb-2020

Sorry.We do not make customized products. Answered by A.R, 09-Feb-2020 09:10 AM

Q: I bought this sensor few days ago...Bt im getting reverse value...means im getting 1000 on white surface & below 100 on black surface, while we get 1000 on black surface & below 100 on white surface.Is this value is correct for ur sensor or manufacturing defect of ur product Questioned by raihanjami, 22-Jul-2020

The sensor is OK. it's working just the way it is designed to work which is giving high voltage output over white surface and low voltage output over black surface. Answered by techshopbd, 23-Jul-2020 10:57 AM

yes.I have found the solution through your data sheet later on. Answered by raihanjami, 23-Jul-2020 15:57 PM

Q: problem is, the sensor can not detect any line. it's continuously showing 0 for the digital read. and -10 to 15 for the analogue read. what to do now? Questioned by ovijit.mte.kuet@gmail.com, 25-Jul-2021

Q: Do they work out of the box with the new/updated Polulu QTR-A library examples? Or do we have to modify anything for it to work? Questioned by s1nisteR101, 14-Jul-2022

Q: How much is the spacing between adjacent sensors? And how much is the total length? It's specifications are copied from of the array if 6. Questioned by mohosinmahmud9602@gmail.com, 09-Jul-2023

1 cm spacing between two adjacent sensors, covering 9cm distance by the entire sensor array. Answered by almamun3248, 11-Jul-2023 17:37 PM

Q: does it come with soldered pins? Questioned by rajinsalehin55@gmail.com, 29-Sep-2023

Here is using the "Male Header Connector Single Row (Yellow)" connector . You can work using Jumper War male to female or female to female. Answered by Atiqur_ORELCO, 30-Sep-2023 09:01 AM
