Name: Rain Drop Sensor Module HW-028 for Arduino
Brand: Chinese
SKU: 52669
Availability: InStock

Description

Upgrade your DIY electronics projects with this High-Sensitivity Rain Drop Sensor Module. Designed seamlessly for Arduino, Raspberry Pi, ESP32, and other microcontrollers, this sensor is the perfect solution for detecting rainfall, snow, or water droplets. Whether you are building a smart weather station, an automated irrigation system, or smart windshield wipers, this module offers reliable performance with dual output modes (Analog and Digital).

The kit includes a nickel-plated sensing board (Model HW-028), a control module based on the reliable LM393 comparator chip, and jumper cables for immediate connectivity.

Key Features & Benefits of the Rain Drop Sensor Module

Anti-Oxidation Design: The large sensing board ( $5cm \times 4cm$ ) features high-quality nickel plating, offering superior conductivity and resistance to oxidation/corrosion compared to standard copper tracks. This ensures a longer lifespan, even in humid outdoor environments.
Dual Output Modes:
- Digital Output (DO): Sends a simple High/Low signal (0 or 1). Perfect for triggering a switch (e.g., “If raining, close window”).
- Analog Output (AO): Provides a real-time voltage signal indicating the intensity of the rainfall.
Adjustable Sensitivity: Features an onboard potentiometer (blue trimmer), allowing you to calibrate the sensor’s sensitivity to ignore light mist or detect the slightest drizzle.
Stable Performance: Powered by the LM393 Comparator, ensuring clean signals and a driving ability of over 15mA.
Visual Indicators: Equipped with a Power LED and a Digital Output trigger LED for easy debugging and status monitoring.
