Rain Drop Sensor Module

The Raindrops Detection Sensor is an electronic module designed to detect rainfall through a dedicated rain board and a control module based on the LM393 comparator. It provides both analog and digital outputs, allowing flexible integration with microcontrollers and control systems. The sensitivity can be adjusted using an onboard potentiometer to suit different environmental conditions. This sensor is commonly used in automotive systems for automatic windshield wipers, agricultural rain detection, and home automation applications.
