Auto-Calibrating Line Sensor

From the shop's description

his newly developed Auto-calibrating line sensor is super easy to use. Come with 5 pairs of IR transmitter and receiver, it can cover line detection of 1cm to 3cm wide, dark color or bright color line. With 1 press, it will start “recognizing” the surface under it, calibrating the threshold between dark and bright. it takes 4 to 5 seconds only. After that, it is done, being stored in internal nonvononvolatiley, it will still “recognize” the line even after power off and on again. Come with connector and wires. Features: 5V power 5 digital output representing logic of 5 IR sensor 1 press to start calibration 2 press to toggle logic into Dark On mode, to sense dark line 3 press to toggle logic into Bright On mode, to sense bright line Calibration button for easy of calibration Combine with MC40A for line following robot development Arduino lover, checkout the new 2A motor shield, it comes with socket for LSS05 Optional Breakout board to standard 0.1″ pad, BB-2020-08H Download the User’s Manual for more information.
