TVOC MH-Z19B

mh-z19 · PyPI Mar 24, 2021 · Features about calibration (both MH-Z19 & MH-Z19B), detection range change (MH-Z19B) and ABC logic on/off (MH-Z19B) are implemented at version 0.2.1 or later. I'm afraid I've just only implemented these without test due to lack necessary devices and apparatus for the test, fx: standard concentration CO2 gas, also MH-Z19B module.
