This neat little module combines 3 IR Line follower sensors into one PCB to be able to detect the position of the line, you can also confirm when the line is directly in the center with the third one.

This module is powered from 3V3 and then produces 3v3 Logic out. 

 We recommend the sensor is between 1-3CM above the line and that the line is between 1.8-2.5CM Wide. Above the black line the output will be low and above should be high. This is indicated with the LEDS & The sensitivity can be adjusted using the potentiometer & screwdriver.

 

To connect to your Raspberry Pi connect 3V3 to the 3V3 power on the Raspberry Pi (Pin 1), Ground to GND on the Raspberry Pi (Pin number 6 / third down on right)

Then connect the 3 outputs to three logic pins you wish. We recommend you do not use 11,12,15 or 16 as they would conflict with our motor board. We would suggest 19,21 and 23. You can also connect 3v3 to 17 and ground to 25 keeping all 5 pins in one row.

If you need more power you can also use 5V into the sensor's VCC but still produces only 3.6V on the logic channels.

 

 

Thanks to Zachary Igielman for testing this module for us.

Excellent, easy to use, accurate sensor. Team 3.14 Musketeers used this on our Pi Zero robot B'Otagnan which won the line following challenge overall at Pi Wars 2017.

    Excellent module, performs perfectly

    A great little module that gives you a bit more control than the two sensor ones. fast and efficient delivery from Ryanteck as always.

      Just what was needed to help our robot do the line following challenge in the PiWars competition.

        Winner!

        Third robot being built for #PiWars. This is the third line-follower sensor purchased from Ryanteck. KEITH Evo won the line following challenge in 2015. Nuff said...

            Great module.

            This is an accurate, very simple module that worked perfectly after just half an hour of coding! The calibration potentiometer is a life saver, three IR sensors gives a more accurate result and greater control, it's easy to mount with the screw holes, the LEDs on top allow a human to understand at a glance what the robot 'sees' and it's very simple to wire up.

              It Works!

              Nicely made, easy to mount and does exactly what it is supposed to. Our PiBot now happily follows a black line. The potentiometer allowed some fine tuning.
              Sent out and delivered very promptly.

                Very good looking piece of kit

                Very good looking piece of kit (for a circuit board!) and works as we wanted. Still to be permanently installed in our home-grown robot, but confident of success!
                Ordering and delivery easy and fast.

                  Excellent, easy to use and having the LEDs on top makes it trivi

                  A really neat bit of kit. Works at 3v3 so is Pi-friendly out of the box. The three central pins provide a straight forward high/low (on /off) making it trivial to determine where a black line is that's being followed. Nicely made, can see this bolting onto many a robot. Suggest using with something like Slice of Pi/O as it does consume 3 of your precious GPIOs though, but having said that, it'll work fine with a vanilla Pi too. The potentiometer is pretty handy to adjust the sensitivity and is a welcome addition to the board. Recommended.
