Description

The concentration of carbon dioxide (0.03 % usually) 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 carbon dioxide gas concentration is becoming a universal research topic. DFRobot released its latest high-precision infrared Arduino co2 sensor The effectively measuring range is from 400 to 5000 ppm. This sensor is based on non-dispersive infrared NDIR technology and has good selectivity and oxygen-free dependency. Besides, its service life could be up to 5 years!

n addition, this Gravity: Infrared CO2 Sensor For Arduino (400~5000 ppm) is a high-performance sensor that combines the technology of mature infrared absorption gas detection with precision optical circuit design as well as sophisticated circuit design. It has characteristics such as high sensitivity, high resolution, low power consumption, fast response, anti-water vapor interference, no poisoning, high stability, and long life.
