Juerd Waalboer fe392acfbd Change type for consistency
(Now it's inconsistent with the char* in readBytes, but at least it's
consistent in this file...)

Thanks, supakeen!

Also changed the type for the returned value.

Also, I learned that empty () after [] are optional; reduces linenoise a little.

Juerd Waalboer 6f4ac2b01b Experimental support for mystery sensor 2020-12-15 02:25:24 +01:00
Juerd Waalboer 6c7bb2c4a3 Deal with weird MH-Z19(B?) version
This one, with version number 0436, has a magic "I'm still booting" value
of 436 PPM instead of 410 PPM.

Interestingly, another sensor with version 0430 returns 430 for an instant,
but then goes to 410. During the short 430-phase the clamped CO2 value is
actually 0, so it doesn't require checking.
