Smart Water Tank Level Monitor & Thermal Expansion Project Kit with Arduino Uno

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

Bring a textbook concept to life: prove that a metal rod expands when heated, then turn that principle into a working water tank level monitor. This kit guides you through building a real-time monitoring system with an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and a DS18B20 temperature probe. You will measure a rod's length before and after heating, watch the change on an LCD, and understand thermal expansion as never before.

What You'll Build

You'll assemble a complete Arduino-powered monitoring station. An ultrasonic sensor points at a vertical metal rod, continuously measuring its height, while the temperature probe is attached to the rod to track heat. The 16x2 LCD displays both temperature and distance in real time. When you heat the rod, you'll see the distance reading shrink—direct evidence of thermal expansion. You'll also program a water tank level alert that lights up the LCD when the "water level" (distance) crosses a threshold, turning a physics experiment into a practical engineering model.

What You'll Learn

• Program an Arduino Uno to read ultrasonic and temperature sensors using simple Arduino sketches
• Calibrate an HC-SR04 sensor to measure small changes in rod length due to heat
• Interpret DS18B20 digital temperature data and display it on a 16x2 LCD via an I2C backpack
• Apply the scientific method to quantify thermal expansion co-efficient and present results for CBSE practicals or science exhibitions

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for CBSE Class 9-12 students performing thermal expansion practicals, B.Tech ECE/EEE first-year students exploring sensor integration, and ATL Tinkering Lab instructors who need a ready-to-assemble STEM project. It is also ideal for science exhibition participants at IIT Bombay Techfest, NIT, or VIT events where a live physics demonstration with Arduino creates a strong impact.
