Pin, Control, or Indicator Description

VCC +5 Volts Power Source

GND Ground or negative power source

DO Digital Output. Goes low when moisture exceeds set threshold.

A0 Analog Output - Zero to five volts. The lower the voltage, the greater the moisture.

Power LED Indicates that power is applied

Output LED Illuminates when moisture has exceeded threshold set by sensitivity adjustment.

Sensitivity Adjustment Clockwise is more sensitive. Counterclockwise is less sensitive.
