Interfacing Gravity Infrared CO2 Sensor with Arduino to Measure Carbon Dioxide in PPM
The increasing concentration of carbon dioxide in the air has become a serious problem now. According to the NOAA report, the ozone CO2 concentration has reached 0.0385 percent (385 ppm) and it is the highest amount in 2.1 million years. This means that in one million particles of air, there are 385 particles of carbon dioxide. This rising level of CO2 has affected the environment badly and led us to face the situation like climate change and global warming.
