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
