Tindie Weblog | The Bee Knowledge Logger


If in case you have performed any knowledge logging utilizing microcontrollers you’ve in all probability realised what options are essential for a profitable knowledge logging platform. The Bee Knowledge Logger has clearly thought of these wants and constructed them right into a neat and inexpensive off-the-shelf module.

The Bee Knowledge Logger is constructed across the venerable ESP32 microcontroller and as such you may program it by way of the Arduino IDE or with CircuitPython. There are heaps of offered examples if you happen to dig into the code part of the linked GitHub repository. Alongside the ESP32 there may be an onboard Actual Time Clock (RTC) utilizing the favored and correct DS3231. The RTC implies that lengthy and time-critical data-logging missions are simply achieved. For those who’ve thought of a long-term logging challenge earlier than, it’s worthwhile to take into account 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 gadget 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 remaining bonus, we like that the repository contains some 3D fashions of the gadget. That is useful if you happen to wished to include it into one other challenge or design an enclosure to maintain your Bee protected!
