    Rock steady air quality sensor module, saved us tons of custom coding
    Got this air quality sensor module to prototype a smart ventilation fan update for a client. Hooked it up via the serial pin headers. It updates the TVOC and CO2 fields synchronously without lagging the MCU loop. Baseline calibration handles ambient shifts nicely right out of the box. Super reliable little board.
