It converts rainwater presence into \u003cstrong\u003edigital and analog output signals\u003c\/strong\u003e that can be used in weather monitoring systems and automation projects. \u003cbr\u003e\u003cbr\u003eThe module includes a \u003cstrong\u003enickel-plated FR-04 sensor board\u003c\/strong\u003e that collects raindrops. As water accumulates, the board’s resistance decreases, resulting in a lower voltage output. A completely dry board outputs maximum voltage (approx. 5V on the analog pin). The included \u003cstrong\u003e12V relay module\u003c\/strong\u003e can directly control external devices like motors, pumps, alarms, or other systems, making it ideal for \u003cstrong\u003eautomatic weather response projects\u003c\/strong\u003e. \u003cbr\u003e\u003cbr\u003eSensitivity can be adjusted using the onboard \u003cstrong\u003epotentiometer\u003c\/strong\u003e.
