README.md

A low cost DIY sound pressure level sensor for use by laymen; the result of my master’s thesis. It allows integration into the existing [senseBox framework][0] but can also function on its own. It’s merely a prototype and there obviously is room for improvement.

Uses a STM32G071 (ARM Cortex-M0+)
Uses a Knowles I²S MEMS microphone
Uses a RFM95 LoRa module (not in WAN mode)

Green printed circuit board inside a propped up white 3D printed case.
