Davide Gironi: January 2014

Jan 25, 2014· MH-Z14 has a PWM output, with a sensitivity range of 0ppm to 2000ppm CO2, an accurancy of ±200ppm. The cycle is 1004ms±5%, given the duty cicle Th (pulse high), Tl is 1004-Th, we can convert it to CO2 value using the formula: CO2ppm = 2000 * (Th - 2ms) /(Th + Tl - 4ms) This library read PWM output, and convert it to CO2ppm.
