Raindrops Detection Sensor Module

Raindrop Detection Sensor Module – Rain Weather Monitoring for Arduino & More

The Raindrop Detection Sensor Module is a reliable and easy-to-use component designed for detecting rainfall and measuring its intensity. Ideal for weather monitoring applications, this sensor converts rain detection into both analog (AO) and digital output signals, making it highly versatile.

This module consists of two main components:

1. Rain Sensor Board – A printed circuit board (PCB) that collects raindrops, creating parallel resistance paths that vary with moisture levels.
2. Control Board with LM393 Op-Amp – Processes the signals from the sensor board and provides both analog and digital outputs.

How It Works:

As raindrops accumulate on the sensor board, they decrease resistance, resulting in a lower voltage output. A dry sensor board outputs the maximum voltage (up to 5V), while increased water presence reduces the output voltage. The LM393 voltage comparator ensures stable and accurate signal processing.

Key Features:

✅ Dual Output – Provides both digital (0/1) and analog AO voltage output
✅ LM393 Comparator-Based – Ensures stable and precise detection
✅ Adjustable Sensitivity – Fine-tune the detection level via the onboard potentiometer
✅ LED Indicators – Power and output status LEDs for easy monitoring
✅ High-Quality Construction – Uses FR-04 double-layer PCB with nickel-plated surface for durability and superior conductivity
✅ Arduino Compatible – Works seamlessly with microcontrollers for DIY and industrial applications
✅ Strong Signal Output – Can drive loads over 15mA
✅ Easy Installation – Features pre-drilled bolt holes for secure mounting

Package Includes:

📦 1 x Rain Sensor Board (5.5cm × 4.0cm, nickel-plated for anti-oxidation)
📦 1 x Control Board with LM393 Voltage Comparator
