common tuning methods for LM393

• The sensor is suitable for soil moisture measurement.
• The blue potentiometer on the module adjusts the moisture threshold. Turn clockwise to raise the threshold (requiring wetter soil to trigger), and counter-clockwise to lower it.
• The digital output D0 can be connected directly to a microcontroller. Read D0 as a logic level (HIGH/LOW) to detect soil moisture state.
