TCRT5000 IR Sensor Module

TCRT 5000 IR Sensor Module
The TCRT5000 IR reflective sensor Module uses TCRT5000 IR Sensor to detect color and distance. This sensor module consists of an IR transmitter & an IR receiver. IR Transmitter continuously emits an IR signal which is then reflected by an obstacle and is then detected by the IR receiver. TCRT5000 Infrared Reflective Sensor Module is often used in line following robots, object sorting Robot because this module can sense if a surface is white or black.
The measuring distance range from 1mm to 8mm, and the central point is about 2.5mm. There is also an onboard potentiometer to adjust the sensitivity. The infrared diode will be emitting the infrared continually when the module is powered ON when the emitted infrared light has not been reflected or the strength is not big enough, the receiver diode will be in the off state, and the output pin i.e. DO will be LOW.

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
