I had to triple check this that I got it right — but senseiron has a new CO2 sensor that has a package size of just 3 x 3.5 x 1.2 mm (!):

That’s small enough that you could stick one on top of two AAA batteries, add a controller with a radio, and have a device slightly bigger than an iPod Shuffle that has a battery life of about a year.
