The concentration of carbon dioxide (0.03% usuallly) is related to daily life. Recently, there's a study showing that the atmospheric CO2 content has reached 0.0385% (385 ppm) which is the highest value since 2.1 million years. The raise of atmospheric CO2 content to some extent results in global c..
The Grove - CO2 Sensor module is infrared CO2 sensor with high sensitivity and 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,..
DFRobot released its latest wide range Arduino infrared CO2 sensor, which effective range is up to 0~50000ppm. This sensor is based on non-dispersive infrared (NDIR) technology and has good selectivity and oxygen-free dependency. It integrates temperature compensation and support UART communication ..
By knowing the concentration of CO2 in the air, we can do something to reduce the Grenhouse Effect and protect our earth. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 ..
