The CO2 sensor module has gold-plated plastic version and aluminum alloy tube version. The principle of NDIR infrared absorption detection of CO2 sensor module is not only oxygen dependent, high sensitivity and strong reliability, but also can detect stable and reliable data even under the harsh temperature and environment conditions. The CO2 sensor module adopts gold plating technology to prevent water and corrosion, and extends the service life of the module. PWM waveform output mode makes reading more convenient.
CO2 adopts advanced NDIR infrared absorption detection principle technology, so that the module has no oxygen dependence, and there is no need to worry about the interference of oxygen on the concentration of CO2. Moreover, it has good selectivity for carbon dioxide and high measurement sensitivity, which makes you have a better use experience in measurement.
