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

The Rain Sensor Module for Arduino is a versatile, compact, and cost-effective solution for detecting rainfall or surface water. It consists of a rain-sensitive sensor plate and a signal conditioning control module using the LM393 voltage comparator, delivering both analog and digital outputs for flexible integration. The Rain Sensor Module for Arduino is perfect for various applications, making it a must-have for hobbyists and professionals alike.

When water droplets land on the sensor grid, they lower the resistance, causing a voltage change that is processed by the LM393 comparator circuit. This makes the module ideal for real-time weather monitoring, smart irrigation, IoT automation, and rain-detection alert systems. Built with robust materials and a wide frequency response, the module offers durability and high sensitivity in outdoor and indoor applications alike.

The Rain Sensor Module for Arduino enhances environmental monitoring with its high sensitivity and reliability, ensuring accurate rainfall detection.
