Introduction
The IR transmitting tube of TCRT5000 sensor constantly launches infrared light. Since the black absorbs light, when the IR transmitting tube shines on black surface, the reflected light is less and the IR rays received by the receiving tube is less. This indicates the resistance is large, the comparator outputs high level, and the indicator LED goes out. Similarly, when it shines on white surface, the reflected light is more, which indicates the resistance of the receiving tube is lower, the comparator outputs low level, and the indicator LED lights up.
* 3-Pin anti-reverse cable included
* Use a comparator LM393 that works stably
* Adjustable sensitivity
* Power light and indicator of digital signal output
Application
The module can be applied to smart tracking car and usually in robot project.
