Experiment showed that the light sensor inside MH-Z19B stops working when MH-Z19B is exposed to an air stream from a heat gun. Interface. Sensor provides UART, PWM and analog output interfaces. Both PWM and analog output provide CO2 measurement result limited by some bounds. UART interface implements one of several protocols. Default protocol ("operation mode 0") is the richest one. Protocol ...
2020-06-29· CO2 sensors need to be calibrated now and then, the default for MH-Z19B being Automatic Baseline Calibration (ABC) to lowest measured values every now and then (day?), which would be assigned the ballpark outside CO2 figure of 400 ppm. This is far from accurate and cannot be used to monitor rise of CO2 in the atmosphere, but is tolerable for inside air quality measurement, where most …
