Tindie Weblog | The Bee Knowledge Logger

When you have finished any knowledge logging utilizing microcontrollers you’ve most likely realised what options are necessary for a profitable knowledge logging platform. The Bee Knowledge Logger has clearly thought-about these wants and constructed them right into a neat and reasonably priced off-the-shelf module.

The Bee Knowledge Logger is constructed across the venerable ESP32 microcontroller and as such you’ll be able to program it by way of the Arduino IDE or with CircuitPython. There are heaps of supplied examples for those who dig into the code part of the linked GitHub repository. Alongside the ESP32 there’s an onboard Actual Time Clock (RTC) utilizing the favored and correct DS3231. The RTC signifies that lengthy and time-critical data-logging missions are simply achieved. If you happen to’ve thought-about a long-term logging challenge earlier than, you recognize you must think about energy consumption. The Bee knowledge logger has twin low-dropout regulators and a few intelligent deep sleep energy administration leading to very low energy consumption when sleeping. On the product web page, we are able to see the system is rated to attract a mere 21.3uA — that’s 21 millionths of an amp.  With a connector for a single-cell LiPo battery and an onboard cost controller, it’s fairly trivial to arrange a long-duration data-logging challenge.

With this stage of effectivity and energy administration, you would possibly start to fret about knowledge storage. The Bee Knowledge Logger has an SD card slot on board which is able to settle for SD playing cards as much as 16GB in measurement. 16GB equates to an enormous quantity of knowledge, greater than sufficient for many. Rounded out with twin STEMMA/Qwiic connectors you’ve gotten a variety of sensors for this platform.

As a last bonus, we like that the repository contains some 3D fashions of the system. That is helpful for those who wished to include it into one other challenge or design an enclosure to maintain your Bee protected!
