The carbon dioxide concentration, typically around 0.03%, plays a significant role in our daily lives. However, recent studies have revealed a concerning trend. The atmospheric CO2 content has reached an alarming level of 0.0385% (385 ppm), the highest recorded in the past 2.1 million years. This rapid increase in atmospheric CO2 content is directly contributing to global climate change. Consequently, accurate measurement of carbon dioxide gas concentration has emerged as a universal research focus.

DFRobot released its latest high-precision infrared Arduino CO2 sensor. The effective measuring range is from 400 to 5000ppm. This sensor is based on non-dispersive infrared (NDIR) technology and has good selectivity and oxygen-free dependency. Besides, its service life could up to 5 years!

 

In 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.


This Gravity: Infrared CO2 Sensor is able to directly compatible with the DFRobot Arduino IO expansion board thanks to its external DFRobot Gravity interface. This character simplifies the use of the sensor as it is plug and play and no need additional wiring.

This CO2 Sensor could be widely used in HVAC, indoor air quality monitoring, industrial process, and security protection monitoring, agriculture, and animal husbandry production process monitoring.

In addition, we also have a 0~50000 ppm wide-range infrared sensor with Gravity UART interface, Compatible with Arduino, Raspberry Pi, and other microcontrollers: Gravity: UART Infrared CO2 Sensor (0~50000ppm).
