Carbon dioxide sensor is a kind of gas detection instrument, mainly used to measure the content of carbon dioxide in the air. When the content of carbon dioxide is too much or too little, carbon dioxide sensor will issue an alarm according to its prompt to take appropriate measures to adjust the air quality so as to meet people's own requirements. The non-dispersive infrared (NDIR) principle is used to detect CO2 in the air, which has good selectivity and no oxygen dependence, long life, intelligent and universal, and small volume. Built-in temperature compensation, digital output and analog voltage output, convenient to use. It is mainly used in daily production and life, and plays an important role in creating a good atmospheric environment for people.
