Arduino Uno Cryogenic Temperature Logger Kit: Capture -200°C to +300°C with Research-Grade RTD Precision

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

Measure temperatures from liquid nitrogen cryogenics to high-temperature ovens with research-grade accuracy. This kit guides you through building a 4-wire PT100 RTD-based logger that captures timed data on a microSD card, perfect for physics labs, material testing, or any project demanding extreme-range temperature monitoring with sub-degree precision.

What You'll Build

A self-contained instrument that displays real-time temperature on an OLED screen and logs timestamped readings to a microSD card. The 4-wire Kelvin connection eliminates lead resistance errors, while the ADS1115 16-bit ADC and precision 0.1% resistors inside the Wheatstone bridge give you millidegree resolution. You'll have a tool that can hang on the wall of a cryostat or sit beside a furnace—and survive both.

What You'll Learn

• Designing and calibrating a Wheatstone bridge for a 4-wire PT100 RTD across its full -200°C to +300°C range
• Using ADS1115 16-bit ADC with programmable gain to resolve microvolt changes from the bridge
• Implementing I2C communication for OLED display and DS3231 real-time clock modules
• Writing robust Arduino firmware that manages SD card logging, timestamping, and error recovery

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

B.Tech ECE/EEE students who need a professional-grade measurement tool for final-year projects, physics undergraduates building cryogenic experiments, and participants in Smart India Hackathon challenges centred on sensor instrumentation. It’s the same circuit architecture used in industrial temperature loggers, scaled for your lab bench.

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.
