A: Approximately 500 Hz (2 ms response time). You can read it reliably at intervals of 10 ms or more.
If your FC-51 module is not performing as expected, review the following debugging steps: Scenario A: The Obstacle LED is always ON
The module operates based on . An onboard IR LED (the transparent transmitter) continuously emits infrared light. When an object enters the detection range, the light bounces off the object's surface and is captured by the IR receiver (the black photodiode). Go to product viewer dialog for this item.
