Anyone with a MH-Z14? - Sensors - Arduino Forum

May 06, 2021 · Anyone with a MH-Z14? eXistenZ February 23, 2016, 5:23pm #1. My MH-Z14 CO2 sensor seems unreliable. Does anyone have any experience with these things? The PWM output is easy to convert to ppm, but the dutycycle stays the same, more or less. Am I the first person to be ripped off by the chinese selling me cheap junk?
