Rain Drops Detection Sensor Module – High Sensitivity Water Level & Rain Weather Module for Arduino in Pakistan

Overview 

The Rain Drops Detection Sensor Module is an easy-to-use tool for detecting moisture and rainfall. It consists of two parts: a large, high-quality Nickel-Plated sensing board and a control module powered by the LM393 voltage comparator. The nickel plating is crucial—it resists oxidation and corrosion far better than standard copper, ensuring your sensor survives many rainy seasons.

Key Features 

• Dual Output Mode: Get a simple “Yes/No” via the Digital Output (DO) or measure the intensity of the rain via the Analog Output (AO).

• Anti-Oxidation Design: The sensing pad is treated to resist rust, ensuring a longer lifespan when exposed to water.

• Adjustable Threshold: Use the on-board blue potentiometer to set the exact “rainy” level that triggers your alarm or motor.

• Large Sensing Area: The $5.0 \times 4.0 \text{ cm}$ board provides a wide surface to catch even the smallest droplets.

• Plug-and-Play: Comes with jumper wires for immediate connection to your Arduino, ESP32, or Raspberry Pi.
