The problem
Indoor air quality and comfort are invisible until something is already wrong.
What I built
- An ESP32-WROOM device with DHT11, MQ135, BH1750 and SCD30 sensors in a 3D-printed enclosure designed in Onshape.
- Arduino (C++) firmware sending readings over WiFi (HTTP POST) and I2C.
- A PHP API and MySQL database, plus a Streamlit dashboard with historical graphs and configurable alerts.
