Rain Drop Detection Sensor Module

The rain drop sensor module is a practical and easy-to-use solution for detecting rain and water droplets in electronic and automation projects. Designed for reliability and simplicity, this module is widely used in weather monitoring systems, smart automation setups, and educational electronics experiments.

This rain drop sensor works by detecting the presence of water on its conductive surface. When raindrops or moisture fall onto the sensor plate, the resistance changes, producing a signal that can be processed by the control module. The sensor provides both analog and digital outputs, making it compatible with popular microcontrollers such as Arduino, ESP8266, and Raspberry Pi.

The onboard sensitivity adjustment potentiometer allows users to fine-tune the detection threshold based on environmental conditions. This ensures accurate detection whether the application requires early rain sensing or heavier water presence. LED indicators provide clear visual feedback for power status and detection output, simplifying setup and testing.

Built with durable materials, the module performs consistently in outdoor and indoor environments. Its compact size and low power consumption make it suitable for battery-powered projects and embedded systems. The rain drop sensor is commonly used in automatic wiper systems, weather alert devices, irrigation controllers, and smart home automation projects.

Whether you are developing a weather station, learning sensor interfacing, or building an automated response system, this module offers dependable performance and flexible integration. Its simple interface and adjustable sensitivity make it a valuable addition to any electronics toolkit.
