Humidity Sensor Module – OKY3435

The OKY3435 rain sensor module is designed for reliable weather monitoring and moisture detection. It utilizes a dedicated sensor plate and control board to provide a clear indication of rainfall for various electronics projects.

Key Features
- Features a large 5.5 x 4.0 cm sensor plate (FR-04) for a wide detection area.
- The sensing surface is nickel-plated to protect against oxidation and ensure long-term conductivity.
- An integrated LM393 comparator provides a clean, stable, and reliable output signal.
- Detection sensitivity can be easily adjusted using the onboard potentiometer.
- Offers both a digital (ON/OFF) output for simple threshold detection and an analog output for measuring the intensity of rainfall.

Applications
With its versatile dual-signal output, this module is ideal for integration into microcontroller-based systems. It is commonly used with platforms like Arduino to build automated weather stations, smart agriculture systems, automatic windshield wipers, or retractable roof controllers.
