## Description

This sensor incorporates two QRE1113 infra-red reflectance sensors on a single PCB, spaced just the right distance apart to build a line following robot.

 The PCB is symmetrical with snap-off holes across the middle, so you can either use it as a pair or snap it in half to have two separate reflectance sensors.

## Features

- Analog output shows light or dark surface detected
- Perfect for line following robots
- Easy interface with Arduino
- Dimensions: 37mm x 9mm x 3mm
