The 5-Channel IR Tracker Sensor is an array of 5 IR sensors that are configured and read as digital bits. The 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 the trigger threshold, which detects changes in the angle of the curve track. The 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 an 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 detection, black is active at LOW level, and white is active at HIGH. The detection height is 0-3 cm. This tracking sensor integrates 5 infrared probes, equivalent to 5 single tracking sensors, which makes the car track the line more smoothly
