OSOYOO Infrared Line Tracking Sensor Module + 7 Pin 25cm Female to Female Jumper Wire, 5-Channel Infrared IR Line Reflection Tracker Sensor 3.3V-5V, Smart Car Black White Line Detection Tracing - 2021002100

• The OSOYOO 5-Channel IR Tracker Sensor is an array of 5 IR sensors that are configured and read as digital bits. The OSOYOO 5-Channel IR Tracker Sensor can adapt to many complex environments, users can adjust the on-board sensitivity potentiometer according to the actual situation to modify trigger threshold, which detecting changes in the angle of the curve track. On board 5 channel infrared tracking probe can simultaneously detect the middle track line and detect the left and right edges. This IR reflective sensor utilizes a ITR9909 to detect color and distance. The working principle is to use the different reflectivity of infrared light to color, converting the strength of the reflected signal into a current signal. During the detection, black is active at LOW level, and white is active at HIGH. The detection height is 0-3 cm. This tracking sensor integrated 5 infrared probe, it is equal to 5 single tracking sensors, which makes the car tracking the line more smoothly.
