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 ...

There are sensors out there, sold as MHZ19B, that seem to use the original firmware, but with different hardware. The hardware differs with the original MHZ19B in the following ways: Case: No circular bump over the lamp (a faint impression can be seen under an angle) No raised edges around the square "windows" Slightly more yellowish gold color; PCB: Black instead of green. This is the most ...
