The onboard LM393 comparator acts as a threshold detector. There is a small potentiometer (blue component) on the board. You can adjust this to set a specific humidity level.
Please paste the YL-105 datasheet text or a link (or upload the file), and tell me what you want from the review — e.g., accuracy check, summary, key specs extraction, comparison to alternatives, or suggestions for improvements. If you want a quick summary without uploading, say so and I’ll assume standard review points (electrical specs, mechanical, safety, typical application). yl-105 datasheet

For precise measurements, you must calibrate the sensor by measuring its analog output in known low and high humidity environments and mapping those values in your code. The onboard LM393 comparator acts as a threshold detector
