From the project

Air quality monitoring project based on ESP32C6 with BLE and Matter support + SwiftUI companion app

Airy is a from-scratch air quality monitor built around the Seeed Studio XIAO ESP32-C6. This embedded project covers the full chain end to end: component selection, schematic and PCB design, a custom 3D-printed enclosure, fault-tolerant FreeRTOS-based firmware, a rich BLE protocol, Matter smart-home integration, on-device history storage, and a native SwiftUI iOS companion app.
