Monitor Perishable Transport Temperatures with the Cold Chain Data Logger Kit – Arduino Nano + DS18B20 + RTC

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

In India’s farm-to-fork supply chain, temperature excursions during transport spoil nearly 16% of fruits and vegetables. This kit puts a professional-grade cold chain logger in your hands. You’ll assemble a dual-channel DS18B20 system that timestamps every reading from an RTC, displays live temperatures on an OLED, and stores all data to a microSD card — exactly the kind of tool used in refrigerated trucks and vaccine carriers.

What You'll Build

You’ll create a portable, battery-powered temperature data logger that records from two waterproof DS18B20 probes every 5 minutes. All readings are saved with exact date and time from the DS3231 RTC module, ready for analysis in any spreadsheet. The 0.96-inch OLED gives you instant visibility of both sensor channels and system status, so you know the logger is working without needing a laptop.

What You'll Learn

• Interface multiple 1-Wire DS18B20 sensors with Arduino Nano and manage device addressing
• Configure a DS3231 real-time clock to timestamp sensor readings accurately for cold chain auditing
• Write data to microSD cards in CSV format for post-trip analysis and compliance reporting
• Optimise battery life for long-duration logging runs using sleep modes and efficient coding practices

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students tackling physics or computer science investigatory projects on cold chain monitoring will find every component and a clear path to a working prototype. B.Tech ECE/EEE undergraduates can use it for mini projects, Smart India Hackathon problem statements on agriculture, or IoT lab assignments. ATL Tinkering Labs and NIT/IIT/VIT hobby clubs can quickly deploy a multi-sensor logger to demonstrate real-world embedded systems design in cold storage, dairy, or pharmaceutical transport.

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.
