Raindrop Sensor LED Display Kit — See Rainfall Intensity Light Up with Arduino

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a desk gadget that reacts to the sky. As the first drops hit your window, one LED glows dimly. When a downpour begins, all five shine bright in a cascading display. This kit turns a simple rain sensor into a real-time rainfall intensity meter—perfect for young weather enthusiasts, a school science model, or a quick afternoon maker project with the family.

What You'll Build

You’ll build a stand-alone visual rainfall display. The rain sensor detects moisture on its surface, and the Arduino reads that changing signal. Five LEDs light up progressively: a gentle drizzle activates only the first LED, steady rain moves to the third, and heavy rain makes all five blaze. It’s a tangible, immediate way to see data without a screen, sparking curiosity about analog signals and environmental sensing.

What You'll Learn

• How a resistive rain sensor works and generates an analog voltage
• Reading analog inputs with Arduino and mapping values to LED brightness
• Controlling multiple LEDs using PWM to create smooth dimming effects
• Building a simple weather station circuit on a breadboard without soldering
