Project Aura operates as an integrated, plug-and-play environmental sensing station centered around the Waveshare ESP32-S3-Touch-LCD-4.3 main controller board. The system's primary sensory input comes from the Sensirion SEN66 all-in-one environmental sensor module, connected via an Adafruit SEN6x breakout adapter board, which measures comprehensive air quality parameters such as particulate matter, carbon dioxide, and volatile organic compounds. Optional expansion is supported through the Seeed Studio Grove SFA30 formaldehyde sensor module for targeted pollutant tracking, alongside an Adafruit BMP580, DPS310, or BMP581 barometric pressure sensor to capture atmospheric changes. The ESP32-S3 microcontroller gathers data from these I2C and digital peripheral sensors, processing the raw telemetry internally. A custom firmware running the LVGL graphical user interface renders real-time charts, metrics, and system status directly onto the integrated 4.3-inch touch display. Additionally, the ESP32-S3 utilizes its onboard wireless capabilities to transmit this data over Wi-Fi using Home Assistant MQTT Auto-Discovery support. This allows the hardware to seamlessly integrate into broader home automation networks without requiring manual topic configuration, enabling automated triggers for ventilation systems or remote environmental tracking from any smart device dashboard.
