It logs temperature and humidity to external EEPROM, displays current readings and a history graph, and runs for over a week on a small Li-Po battery using deep sleep with RTC-based wake intervals. The project includes custom KiCad PCB schematics, OpenSCAD 3D-printable enclosure files, and PlatformIO firmware using the Arduino framework. Known issues include battery state-of-charge inaccuracy and a low-battery unrecoverable state, while limitations include no wireless connectivity and display unreliability below 0°C. ## Full article daily.dev links to this article rather than hosting it.
