Integrated a particulate matter (PM) sensor - Sensirion SPS30 - into my envbox build. This should hopefully give me some insight into the dust buildup / particulates in the air around where my miners are running.
Ran out of available GPIOs on the original ESP32 “CYD” board, so spun this up as a separate “dustbox“ unit for now. Will be getting a different ESP32 board with more available GPIOs next most likely - to bring this all back onto a single MCU board, and reduce the overall footprint.
