Tip
We've released the Seeed Gas Sensor Selection Guide, it will help you choose the gas sensor that best suits your needs.
The Grove - CO2 Sensor module is an 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.
Note
IThe sensor value only reflects the approximated trend of gas concentration in a permissible error range, it DOES NOT represent 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 aim to obtain the gas concentration at a very precise level, then we do not recommend this gas sensor.

Thanks for the fast reply! Page 4 of the english datasheet shows a table of the pinout of the sensor: Pad5: UART (RXD) 0-3.3V input digital. Has the sensor been tested with 5V logic at Pad5? Regards, Eric
