I've got one of the simpler models of the Enviro+ (mine's just the plain "Enviro") but it's got the pressure sensor mentioned as well as a gas detector which might be suitable for tracking canine methane emissions. I don't have things automagically running and mine's indoors so I don't have any cool data to share but I've been happy with mine if anyone's looking for similar hardware.
