Mobile Air Quality Measuring Device

This mobile sensor was originally made to be integrated into another project, but possesses the capability to work as a standalone product. It uses a Seeed Grove Air Quality Sensor to return a quantitative value, and that value is further stored to and SD card. It reads the quality every 10 seconds, but is modifiable to the use's needs. The system is toggled with a SPDT switch, with corresponding led bulbs to give visual feedback on what state is selected.
