            Cloud-Based Air Quality Sensing
                    Adafruit's QT PY Wi-Fi and QT breakout boards utilize Sensirion's SCD40 CO2 and SHT40 RH and temperature sensors
    

Adafruit's cloud-based communication setup for air quality monitoring of CO₂, humidity, and temperature ranges features Sensirion’s sensors: the SCD4x series (SCD40) for CO₂ and SHT4x series (SHT40) for relative humidity (RH) and temperature. Adafruit’s easy-to-use QT breakout boards contain the sensors, the QT PY ESP32-S2 Wi-Fi board for communication to the cloud, and Adafruit.io for the cloud dashboard. The boards simply plug together with cables and the QT PY sends the sensor data to the cloud. The data is then displayed on the dashboard using a laptop or tablet.

Demo Setup - Software Used

Adafruit IO as the cloud dashboard:
- Displays data from DigiKey's and Sensirion's booths
- Commercial version provides for frequent updates ($10/month)
Use default Arduino drivers from Sensirion’s GitHub open-source support
