In this guide, you'll discover how to take your data files from a text format like JSONL, CSV, or even TSV into your favourite data analysis software, and start on that scientific charting adventure.
If you already have your data file(s) - feel free to skip to the next page, or keep reading and see where the example data has come from (hint: it's getting even easier to log data these days)!
Just remember, before removing memory sticks, SD cards, or USB drives from data loggers, it's usually best to shut down the data logging device and remove the power before removing the memory storage device. On computers like Windows, use Eject to ensure it's safe to remove cards and drives.
Data Loggers - Adafruit WipperSnapper Offline-Mode
Below demonstrates using data collected using Wippersnapper Offline-mode, which turns your Microcontroller board plus connected SD card, optional real-time clock, and bundles of Analog and Digital components and I2C sensors, into an offline data logging superstar. There's a whole separate guide about it you can check out here:
The next page will briefly outline the assembly of an example setup, which, with minor alteration, could be used for many data logging projects.


There will be three "weatherproof" sensors connected through cable glands, and one breakout board version of a temperature sensor inside the waterproof container.Â
- Two âweatherproofâ DS18B20 temperature sensors will be connected to pins D13 and D14 using Stemma cables connected to DS18B20 chainable breakouts for their convenient screw terminals.Â
- A weatherproof mesh enclosed SHT30 (temperature and relative-humidity) will connect via I2C.Â
- An MCP9808 temperature sensor, which will be inside the container, will also connect via I2C using a StemmaQT cable (JST-SH 4-pin).
These are the remaining components used:




It's worth mentioning that the weatherproof SHT30 comes with individual wires (and ferrules) instead of the convenient Stemma QT connector.
You can connect it any way you know how, like solder it directly to a Stemma QT cable.Â
Those additional parts needed to attach the SHT30 are not mentioned in the list above.
I found it best to solder a Stemma QT cable to a 4 position screw terminal, so I can easily attach the loose wires of the SHT30.
