Bringing Ideas to Life with DIY IoT: Visualizing Noise Pollution with a Raspberry Pi and Python
summary
Build uses a Raspberry Pi with an Enviro sensor microphone, a Python script that computes RMS → sound pressure → decibels every second, and data sent to InfluxDB and Grafana running in Docker. The system logs high-volume timestamped readings (accidental loop produced a flood), shows real spikes (all-time high 97 dB from lightning, recent 96 dB), dashboards count events above 80 dB and daily cycles, and the end-to-end setup works for monitoring and analyzing local noise nuisance.
