MiCS-4514 Gas Sensor

One sensor, four gases. I have not done any "challenge" tests. After 8 days of operation: CO and Ethanol have been ZERO, 100% of the time. (a proper result). NO2 consistently showed 0.25 ppm for week 1 in my "office", It dropped to ZERO after I moved the Air-1 to the kitchen and has remained there for the last 24 hours. As far as I can tell the NO2 readings do not correlate to the SENS55 NOX readings. The NH3 reading spike on occasion. Since moving the Air-1 to the kitchen all of the NH3 spikes are "instantaneous", i.e they appear as vertical lines across time. As I am exploring the limits of my understanding of the true meaning of these gas readings, I continue to stay connected to the Apollo Automation Discord server.

I installed this and absolutely love it. So easy to setup and excellent build quality. I ordered a few more to place around my house. Keep up the great work.
