Module function introduction:
The TCRT5000 infrared emission diode sensor continuously emits infrared light.
Infrared rays are emitted when the intensity of the reflection is not reflected or is not large enough.
The light activated triode is always off.
At this point, the output of the module is high.
Indicating that the diode is off;
The detected object appears within the test range.
The infrared rays are reflected back, and the intensity is large enough.
Light activated triode saturation,At this point the output of the module is low, indicating the diode light.
