DFRobot released its latest wide range Arduino infrared CO2 sensor, which effective range is up to 0~50000ppm. This sensor is based on non-dispersive infrared (NDIR) technology and has good selectivity and oxygen-free dependency. It integrates temperature compensation and support UART communication mode. Most importantly, the product is easy to use; it is compatible with all types of microcontrollers with UART port, like Arduino, Raspberry Pi and other microcontrollers. Besides, it has a long service life, up to 5 years!
In addition, this UART Infrared CO2 Sensor is a high-performance sensor that combines technology of mature infrared absorption gas detection with precision optical circuit design as well as sophisticated circuit design. It has characteristics such as wide range detection, high sensitivity, high resolution, low power consumption, fast response, anti-water vapor interference, no poisoning, high stability and long life.
It can be widely used in HVAC refrigeration and indoor air quality monitoring, industrial process and safety monitoring, agricultural and animal husbandry production process monitoring, etc..
DFRobot LCD Keypad Shield with UART Infrared CO2 Sensor
This is a 0~50000ppm wide range CO2 sensor with UART communication port. It supports Arduino, Raspberry Pi and other microcontrollers. In addition, we also have a 0~5000 ppm high precision infrared sensor with Gravity Analog interface, more easy to use: Gravity Analog Infrared CO2 Sensor (0~5000ppm).
