The Grove - CO2 Sensor module is infrared CO2 sensor high sensitivity and high resolution. Infrared CO2 sensor MH-Z16 Is a general-purpose, small sensors , the use of non-dispersive infrared (NDIR) Present in the principle of the air CO2 Detect , with good selectivity, oxygen- dependent , long life， built-in temperature sensor, temperature compensation ，with UART output , easy to use. It can be widely used in HVAC and indoor air quality monitoring , industrial process monitoring and security , agriculture and livestock production process monitoring.

The sensor value only reflects the approximated trend of gas concentration in a permissible error range, it DOES NOT represents the exact gas concentration. The detection of certain components in the air usually requires a more precise and costly instrument, which can not be done with a single gas sensor. If your projects aims to obtain the gas concentration at a very precise level, then we do not recommend this gas sensor.
