Rain Drop Sensor Module

Rain Drop Sensor Module The Rain Drop Sensor Module is a simple and affordable sensor designed to detect rain, water droplets, and the presence of water on its sensing plate. It uses a conductive sensing grid that detects changes in electrical conductivity when water comes into contact with the plate. The module provides both analog and digital outputs, allowing it to be easily connected to Arduino, ESP32, and other microcontroller platforms. An onboard potentiometer allows the digital detection sensitivity to be adjusted according to the application. Key Features: - Detects rain and water droplets - Analog and digital output - Adjustable sensitivity - Built-in LM393 comparator - Easy to interface with Arduino and ESP32 - Compact and low-cost design - Separate sensing plate and control module Applications: - Rain detection systems - Automatic rain alarms - Smart irrigation systems - Weather monitoring projects - Home automation - Water leakage detection - IoT monitoring systems - Arduino and ESP32 projects Wire Connection: VCC – Connect to 3.3V or 5V power supply GND – Connect to GND AO – Connect to an analog input for variable water/rain detection DO – Connect to a digital GPIO for rain detected/not detected output
