TCRT5000 Tracking Line Follower Sensor a4988 56MHz passive ID cards andIntroduction: TCRT5000 sensors continuously emit infrared infrared emitting diodes, infrared rays emitted when not being reflected back or reflected back but the strength is not big enough, the phototransistor has been in a shutdown state, then the output modules is high, indicating diode remains off state; when the object appeared to be detected within the detection range of the infrared is reflected back and the intensity is large enough, the
