CO2 series is a kind of sensor that uses non-dispersive infrared technology (NDIR) to measure carbon dioxide. The products are divided into pump suction type and diffusion type. After the infrared radiation emitted by the infrared light source is absorbed by the gas to be measured at a certain concentration, the spectral intensity proportional to the gas concentration will change, so the variation of the spectral intensity can be obtained to reverse the concentration of the gas to be measured. The infrared carbon dioxide sensor module adopts the NDIR infrared absorption detection principle, combines the advanced optical path, the precision circuit and the intelligent software, forms a CO2 sensor module.
