Capillary Rise Experiment Kit with Arduino Uno – Measure Water Rise Time & Compare Tube Diameters

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

Watch water defy gravity as it climbs narrow tubes while four IR sensors precisely time the rise. This Arduino-powered setup turns a classic physics concept into an interactive data-collection experiment, making it ideal for CBSE science exhibitions, ATL tinkering labs, and STEM classrooms.

What You'll Build

You'll assemble a sensor rig that automatically detects water reaching four preset heights in capillary tubes of varying diameters. An LCD screen displays the rise times in seconds, letting you plot curves and compare how tube size affects capillary action. The whole setup runs on a 9V battery and mounts on a single breadboard.

What You'll Learn

• Calibrate and program infrared proximity sensors to detect water surfaces
• Use the Arduino Uno to capture real-time timing data
• Interface a 16x2 LCD with I2C backpack to display measurements
• Analyze experimental data to understand capillary rise equations (h ∝ 1/r)
