As water bridges the exposed copper traces on the sensing pad, the resistance between the traces decreases — the module converts this resistance change to an analog voltage (0–5V) readable by any Arduino analog input. Widely used for rain detection, water overflow alerts, plant watering automation, and liquid level monitoring in tanks and containers.
