The SMART Box of AURA Project
summary
A compact, solar-powered IoT box that embeds Grove environmental sensor and gas sensors (NOx, O3, CO2, CO) into urban green furniture, sending calibrated captures over MQTT over Wi‑Fi to a central server, storing raw JSON-like payloads and enriching them with ARPA/openWeather APIs. Device boots, self-checks, calibrates, records, uploads, then shuts down to save battery and deliberately discards partial captures on failure. Built from COTS parts and open software, it produces live AQI maps, historical trends and alert bulletins via a Bootstrap web UI.
