Overview

A school IoT project for monitoring library noise at St. Dominic College of Asia. An ESP32 sensor sends sound readings to a dashboard that shows noise levels on a library floor plan.

The demo uses one live ESP32 sensor and four simulated nodes.

Highlights

  • Live noise readings from an ESP32 and an INMP441 microphone.
  • A floor-plan heatmap with quiet, moderate, and loud noise levels.
  • Firebase keeps the sensor readings and dashboard in sync.
