SEN0219

SEN0219 is a high-precision infrared Arduino CO2 sensor. The effectively measuring range is from 400 to 5000ppm. This sensor is based on non-dispersive infrared technology and has good selectivity and oxygen-free dependency. Besides, its service life could up to 5 years. It integrates temperature compensation and support DAC output. The current CO2 concentration can be read with only one digital port. It is easy to use and is compatible with all types of microcontrollers and sensors. In addition, it is a high-performance sensor that combines the technology of mature infrared absorption gas detection with precision optical 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. It is widely used in HVAC, indoor air quality monitoring, industrial process & security protection monitoring, agriculture and animal husbandry production process monitoring.
