20190610· Some time ago I have purchased online carbon dioxide (CO2) sensor module MHZ19b. It’s a cheap and very simple sensor with the UART interface allowing concentration measurement in the range up to 5000ppm. The normal level of CO2 concentration is considered about 4001000ppm. Higher levels lead to various negative effects like a feeling of “bad air” and so on. The concentration of 2000 ...
20211108· Features about calibration (both MHZ19 MHZ19B), detection range change (MHZ19B) and ABC logic on/off(MHZ19B) are implemented at version 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 MHZ19B module. If you have these devices or apparatus and try to use …
