  1. A low cost DIY sound pressure level sensor for use by laymen; the result of my master's thesis. It
  2. allows integration into the existing [senseBox framework][0] but can also function on its own. It's
  3. merely a prototype and there obviously is room for improvement.
  4. * Uses a STM32G071 (ARM Cortex-M0+)
  5. * Uses a Knowles I²S MEMS microphone
  6. * Uses a RFM95 LoRa module (not in WAN mode)
