Really looking forward to using this. Our local Council has a few air quality monitors in strategic places and publish the results as open data. However, they are 6 months behind in publishing data and have recently declared a "air quality emergency". They also state "Currently the level of interest in air quality appears to be rising, but this does not seem to translate into interaction between the Council and the local communities".

With an Enviro+ on a portable Pi I'll now be able to get my figures in near real time and ignore the Council.

This looks great. I've been waiting for a nice, hackable, cheap set of environmental sensors! There's only one "improvement" I would like to see - an option to buy a cheaper version without a display attached. For my application I will not need any display, and it seems a shame to spend resources on one when it's only going to get destroyed by the elements :)

A raspberry is quite an overkill for an environmental sensor. You could achieve the same with an Cortex M4 (minus the microphone).

Can you easily log to influxdb from a Cortex M4 though? That's the big benefit of a RPi from my point of view

Havent heard of it before, but according to wikipedia they accept data input over UDP in a minimalistic format, so I dont see how this would be a problem.
