Gravity: PWM Infrared Carbon Dioxide Sensor (400-5000 ppm) Category_Tools The combination of GNSS andThe concentration of carbon dioxide (0. 03% usually) is related to daily life. Recently, theres 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 climate change. How to accurately measure carbon dioxide gas concentration is becoming a universal research topic.
