[Solved] MHZ19B provides only static max values for CO2 ...

6/5/2021· The repeating output in 15 second cycles shows that the “CO2 High Byte” value and the “CO2 Low Byte” value stay constant for ever obviously at their max level as the calculated PPM value (ppm = (256 * antwortHigh) + antwortLow) is always 5000 ppm. Also the response status = antwort[5] should be 0x40 but is 0x00.
