Product Overview

This Raindrops Detection Sensor Module is designed for reliable weather monitoring and rain sensing applications. It features a high-quality nickel-plated sensing pad for durable performance and provides both digital and analog output signals for flexible integration with microcontrollers like Arduino and Raspberry Pi.

Key Features

• Dual Output: Provides both a digital switch output (HIGH/LOW) and an analog voltage output (AO) for precise rain intensity measurement.
• High-Quality Sensor Pad: Made with FR-04 material (55mm x 40mm area) featuring nickel plating for excellent oxidation resistance, conductivity, and long service life.
• Adjustable Sensitivity: Onboard potentiometer allows fine-tuning of the rain detection threshold.
• Strong Drive Capability: Comparator-based output provides a clean signal with over 15mA driving capacity.
• Easy Installation: Includes mounting holes for secure placement.
• Wide Voltage Compatibility: Operates on 3.3V to 5V power supplies.
