The goal for the second iteration of this project is to make it less centralized. Sensors should be independent of logging and visualization. After version 1.5 this is already achieved partially: database and graphing run on my home server and the sensors are connected to an independent Raspberry Pi. Only reading out a few sensors every couple of seconds is no challenge for the Pi but wastes power. Running a full-fledged operating system for this simple task is just too much overhead – almost every micro controller can do that. Since I know python but I’m not as well versed in Arduino, C or similar, I would like to use a micro controller that can run python. Although python requires higher perfomance by design, there is a number of capable micro controllers out there today. The ESP32 is also overkill in terms of performance but I wanted to play around…
