noisesensor

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)
