Arduino Freeze-Thaw Cycle Data Logger Kit – Log 3 Temperature Probes to SD Card with 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.

Ever wondered how civil engineers test concrete for freeze-thaw damage, or how food scientists monitor cold chain integrity? This kit lets you build a three-probe temperature logger that records readings every few minutes onto an SD card, with precise timestamps from a real-time clock. You’ll be able to place probes inside test materials and capture exactly when water freezes and thaws — a critical factor in everything from pothole formation to crop storage.

What You’ll Build

You’ll assemble a rugged data logger that writes temperature values from three DS18B20 waterproof probes to a CSV file on a microSD card, along with time stamps. Once built, you can monitor freeze-thaw cycles in soil samples, concrete cubes, or frozen foods by simply inserting the probes and letting it run for hours or days. The onboard RTC ensures every data point is tied to the correct time, even after power cycles.

What You’ll Learn

• Interface multiple 1-Wire temperature sensors with Arduino using the OneWire library
• Configure a DS3231 RTC module via I2C and maintain accurate timekeeping
• Write sensor data to a CSV file on an SD card using the SD library, organizing columns for each probe
• Design experiments to detect freeze-thaw transitions by analyzing temperature curves across three probes
