From the project
Smart Air Quality Sensor built using ESP32, SEN66 and ESPHome
The device uses an ESP32 and the Sensirion SEN66 to track 9 different air quality metrics (PM1, PM2.5, PM4, PM10, VOCs, NOx, CO2, Temperature, and Humidity) and displays them on an e-ink screen. It connects natively to Home Assistant and the firmware is written using ESPHome.
