Precision Tipping Bucket Rain Gauge with Arduino Uno — Track Every 0.2mm Tip & Calculate Hourly Rate

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

Monsoon season turns CBSE Class 12 physics projects and B.Tech ECE mini-projects into a scramble for a reliable environmental sensor. This kit eliminates the guesswork. A calibrated tipping bucket mechanism paired with a reed switch generates a precise pulse every 0.2 mm of rain. The Arduino Uno captures those pulses, debounces them, and displays accumulated rainfall and real-time hourly rate on a 16x2 I2C LCD. You get a lab-grade weather station that fits on a breadboard — and a project that stands out at any hackathon or school exhibition.

What You'll Build

A standalone rain gauge that counts every bucket tip, updates total rainfall in millimetres on the LCD, and computes the hourly precipitation rate using a DS3231 real-time clock. The reed switch feeds clean signals to the Arduino, which processes them into meaningful data for immediate reading. The system never misses a tip, even during heavy Indian downpours, and the I2C backpack keeps wiring simple.

What You'll Learn

• Calibrate a tipping bucket mechanism for accurate 0.2 mm resolution
• Interface a reed switch with Arduino and implement debounce logic in code
• Drive a 16x2 LCD via I2C backpack to display live sensor data
• Use DS3231 RTC to timestamp events and calculate hourly rainfall rate
