- Gravity: PWM Infrared CO2 Sensor For Arduino (0~5000 ppm)SKU: SEN0219 Brand: DFRobotThe 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 climate change. How to accurately measure the carbon dioxide gas concentration is becoming a universal research topic.
