# TempTrack

This repository contains the code for an ESP32 with temperature sensors attached, as used in [this project](https://christophhagen.de/projects/electronics/temp-logger/en.html).

The device records measurements at specified intervals and allows reading them over a Bluetooth connection.
It stores the data in RTC memory and wakes itself periodically for measurements.
Bluetooth is enabled at the push of a button, to improve energy efficiency.
