Product Introduction
Carbon Dioxide Sensor CO2 Sensor DS-CO2-20 Overview:
DS-CO2-20 is a digital carbon dioxide concentration sensor based on non-dispersive infrared absorption (NDIR) principle. It can continuously collect and calculate the carbon dioxide concentration in the air per unit volume, and output it in a universal digital interface format. This sensor can be embedded in various instruments or environmental improvement devices related to carbon dioxide concentration, providing timely and accurate concentration data.
Working Principle
The working principle of infrared non-dispersive absorption (NDIR) gas sensors is based on the absorption characteristics of different gas molecules for near-infrared spectra. The gas concentration is determined by analyzing and calculating the relationship between gas concentration and absorption intensity (Lambert-Beer law).
This sensor adopts the non-dispersive infrared absorption principle and uses a single-chamber dual-channel design structure, featuring small size and high detection accuracy.
