This is the Line Tracking Sensor designed for line following robots. The board has two main components IR Transmitter and IR Receiver in one package named TCRT5000. The TCRT5000 are reflective sensors which include an infrared emitter and photo-transistor in a leaded package which blocks visible light. The package included two mounting clips. As you look at the board you can see a Potentiometer or Trimmer which used to adjust the sensitivity of the sensor.
