KY033 TCRT5000 Sensor

KY033 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 high, indicating that the diode has been in the off state; in the object to be detected within the detection range, and the intensity of the reflected infrared rays is large enough, phototransistor saturated, and the output terminal of the module is low, the indicator LED is lit.
TCRT5000 Single Channel Line Tracking Sensor Module is a carrier board for the TCRT5000 reflective optical sensor. Although it is designed for use with line-following robots, it can be used in mini-sumo robots for line control. The board has a digital output.
Applications:
Position sensor for shaft encoder 
Detection of reflective material such as paper, IBM cards, magnetic tapes etc.
Limit switch for mechanical motions in VCR
General purpose – wherever the space is limited
