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.

Questions and Answers

Hi! My name is Carlos, from Spain. I'm working on this new project. Is based on mesure the street's Co2 levels and if is low turn on a green, then if reach a level turn on a yellow led and if it reach the maximum turn on a red led. Is ok for this? Thanks
