TL;DR
Edgar S has created the AIR PRO, a stylish air quality monitor reminiscent of the Pip-Boy from Fallout. This device features a Qualia S3 display driving a round screen and uses a Sensirion SEN66 sensor module to measure various air quality metrics. It tracks CO2 levels, particulate matter (PM1.0 to PM10), volatile organic compounds (VOCs), nitrogen oxides (NOx), temperature, and humidity, updating every two seconds.
