20200730· My sensor is the MHZ16 and is capable of 50,000 ppm. i will need to measure more than 5k ppm. i really need some help here. From my reading of the data sheet, the 1004ms pwm output is scaled to the range of your sensor. If you have purchased the 050000ppm (05%) sensor, then that is what the output should reflect.
20161009· I have a MHZ19 CO2 sensor, according the datasheet I can obtain PPM values via UART and PWM. The difference between both method is the limit in the CO2 concentration, where UART I should have readings between 05000ppm, and via PWM I should have readings between 02000ppm.
