Keyestudio White/Black Line Detector Module
Price: GBP £3.99
This module is ideally suited to white/black line detection, typically seen in line following robots. Sensitivity adjustment and a reduced susceptibility to interference makes this module an ideal candidate for any line robot.
Working at a low 5V input the module will output LOW on detecting a white object and HIGH while not detecting. An onboard potentiometer allows for the detectors sensitivity to be varied. This provides a means of adjusting the module to be more sensitive to particular materials and over different distances.
M3 mounting holes ensure you have some method of mounting the unit to the robot.
IR (Infrared) is in a portion of the electromagnetic spectrum that is invisible to the naked eye. As such testing this module can be troublesome. A nice little trick to help; take a digital camera or smartphone camera and point the camera at the LED while it is lit. You will find most digital cameras show a gentle purple glow from the LED when it is lit.
