Thermal Expansion Measurer Kit with Arduino Uno + Ultrasonic
Build a Working Thermal Expansion Measurement Tool with Arduino Uno and Sensor Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Place a metal rod into this sensor setup, apply gentle heat, and watch the numbers change in real time. This kit turns the abstract idea of thermal expansion into a concrete, measurement-based physics lab. Whether for a CBSE class 12 practical or an ATL Tinkering Lab station, you will collect temperature and displacement data on an LCD screen — all with a single Arduino Uno at the core.
What You'll Build
You will assemble a measurement station where a DS18B20 probe tracks the temperature of a metal rod while an HC-SR04 ultrasonic sensor detects length changes down to millimetres. The readings appear simultaneously on a 16x2 LCD, letting you record exactly how much a rod expands as it warms. It is a complete, self-contained physics instrument you can use for multiple experiments.
What You'll Learn
- How to interface a DS18B20 digital temperature sensor with Arduino and read accurate Celsius values
- How to measure physical displacement using an HC-SR04 ultrasonic sensor and convert time-of-flight to distance
- Understanding calibration and error sources when linking temperature to length change
- Recording real-world thermal expansion data and comparing it with theoretical linear expansion coefficients

Who This Kit Is For
Ideal for CBSE Class 11-12 physics students tackling thermal expansion investigations, ATL Tinkering Lab mentors who want a ready-to-use sensor module, and B.Tech ECE/EEE learners starting out with sensor integration. Perfect for Smart India Hackathon school-level exhibits or as a working model for science fairs where data logging and precision matter.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on your kit box to chat with our AI build companion. If you prefer a human, reach out on WhatsApp — we reply within a working day.
Do I need to supply a metal rod and heat source?
Yes, you will need a metal rod (aluminium or copper works best) and a safe heat source such as hot water or a hair dryer. The kit includes all electronics, wiring, and the sensor rig.
Can I log the expansion data to a computer?
Absolutely. The Arduino serial monitor displays temperature and distance values live, and the included code can be extended to log into a CSV file or send data to a Python script for graphing.
Is this kit suitable for a first-time Arduino user?
Yes, this is a beginner-level project. Every connection is through a breadboard, the code is pre-loaded onto the Arduino, and the AI companion walks you through each step, from component identification to final testing.
DS18B20 temperature and HC-SR04 distance prove thermal expansion of a metal rod under heat.
