Module functions is introduced:
TCRT5000 sensor of infrared emission diode constantly launch infrared,
the infrared ray is emitted when the intensity of reflected back has not been reflected or but is not big enough, the light activated triode has been in the off state, the output end of the module at this time for the high level, indicating diode has been put out state; detected objects appear within the scope of testing, infrared light is reflected back and strength is enough big,
light activated triode saturation, at this time the output of the module for the low level, instructs the diode lights. 

Package Included:
1PCS*TCRT5000 Obstacle Avoidance Track Sensor Infrared Module for Arduino
