Description

The Water Drop Rain Sensor Module is designed to detect the presence of water or rain using a corrosion-resistant sensor pad. It provides both analog and digital outputs, making it easy to interface with microcontrollers like Arduino, ESP32, or Raspberry Pi.

The module includes an amplifier board with a comparator and sensitivity control potentiometer. It’s widely used in weather monitoring systems, automatic wiper controls, and smart irrigation projects.

Features:

• Separate sensor pad and control board

• Analog (A0) and digital (D0) outputs

• Adjustable sensitivity using onboard potentiometer

• Water- and corrosion-resistant sensing surface

• LED indicators for power and output state

• Supports both 3.3V and 5V logic systems

• Easy to integrate with microcontrollers
