Cool little CO2 meter tech cellphone gadget.

Hell yea! I got me one.
That's why I keep my ear to the ground for new tech like this.
I even paid the extra $7 for the faster shipping date.

Can be had for under $20 here. This is an amazing price! temperature, humidity and CO2 detector all in one!

So, was it any good?

I've got one of the bottom ones, but they are difficult to get connected, but they work. I don't think they are extremely accurate in my mind, but it certainly works.

It needs to be controlled though a network.
