I had to take a break from this project to get some other work done, but some new sensors have arrived and progress is happening again... a bit.

I had an idea about using 2 gas sensors and comparing the results to narrow down which gas is being detected, so alongside the TGS2600 I plan to install a MiCS5524. It looks like there's more than enough space for both of them and the DHT-22 even if I make the chin smaller, so I'm looking forward to finding out what they can do. Also I'm not sure about the results from the SI1145 UV sensor in the POD, so Patrick is getting a VEML6070 instead.
