KY033 TCRT5000 Sensor Li-Ion Batteries Witty Fox We think this will makeKY033 TCRT5000 Sensor The TCRT5000 Single Channel Line Tracking Sensor Module is a great detector for a line following robot. Potentiometer to adjust the sensitivity of the individual sensors. TCRT5000 infrared sensor emits infrared emitting diode continuously when no infrared rays emitted or reflected back is reflected back but the strength is not large enough, the phototransistor has been in the off state, and the output terminal of the module is
