In the smart car DIY process, we often use a line tracking sensor to make the smart car follow a line.
The keyestudio 3-channel line tracking module actually is an infrared sensor. The component used is a TCRT5000 infrared tube.
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 HIGH level, and white is active at LOW.
The detection height is 0-3 cm.
We have integrated three groups of TCRT5000 infrared tubes on a single board, convenient for wiring and control.
Turn the adjustable trimpot to adjust the module’s sensitivity.
The module comes with two 3mm positioning holes for mounting on other devices.
Note: before testing, turn the potentiometer to adjust the sensitivity. The sensitivity is the best when make the LED at the threshold point between ON and OFF.
