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 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)
This repository includes
- STL files for the case
- Schematic and PCB layout files
- STM32 code for the G071 microcontroller
- An Arduino library to be used with the senseBox MCU
- An ESP32 library to be used as an alternative to the senseBox MCU
