Air Quality Monitors
Commercial air quality monitors cost around $100 and up.
We created a kit that you can easily put together that cost around $60.
It uses the popular Arduino microcontroller, small display and a sensor that
measures various gases that impact air quality. It provides a measurement of these
air pollutants in parts per million (PPM).
