Rain Sensor for Arduino – Analog & Digital Output Rain Drop

Rain Drop Sensor Module – Analog & Digital Rain Detection for Arduino and IoT Weather Systems

The Rain Drop Sensor Module is a simple and effective way to detect rain or surface water using a conductive sensing pad. It outputs both analog and digital signals, allowing real-time monitoring of rain intensity or presence using microcontrollers like Arduino, ESP32, or Raspberry Pi.

This module is commonly used in smart irrigation systems, weather stations, rain alarms, and IoT environmental monitoring solutions across Bangladesh. The sensitivity can be adjusted with an onboard potentiometer.

Key Features:

• Output: Analog and digital signals

• Operating Voltage: 3.3V to 5V

• Adjustable sensitivity (via potentiometer)

• Separate sensing pad and control board

• Plug-and-play with Arduino and ESP boards

• Detects water drops and rain level

Applications:

• Rain detection for smart irrigation

• Weather monitoring and forecasting systems

• Automatic wiper or canopy systems

• IoT water presence monitoring

• Educational and embedded system projects in Bangladesh

The Rain Drop Sensor Module is a low-cost and reliable choice for integrating rain detection into automation and IoT applications.
