MH-Z14 co2 sensor module questions - Sensors - Arduino Forum

May 06, 2021· Yet I observe that the guy uses PWM output, which for my sensor module only reads from 0 to 2000 ppm, and not the full scale of the sensor. But now that I watched his video I understand that the PWM output will probly be more exact than the analog output, so i'll consider reading PWM tilll 2K ppm, and analog for the rest of the scale.
