MH-Z CO2 Sensors


Ready to use imeplementation for CO2 sensors of the MHZ series (Intelligent Infrared CO2 Module)
Carbon Dioxide modules such as MH-Z14A, MH-Z19B (and maybe some more) are supported on Ardunino / ESP8266. Both output signal modes UART via Serial Port and PWM are suppported. See example and/or manual for wireing the mhz14a or mhz19b.
