1. Product description
FS00902 Sensor is a Multi in one sensor which can simultaneously monitor the concentration of particulate matter and carbon dioxide in the air. The monitoring of particulate matter concentration can continuously collect and calculate the number of suspended particulate matter with different particle sizes in the air per unit volume based on the principle of laser scattering, that is, the distribution of particulate matter concentration, and then convert it into mass concentration. Carbon dioxide concentration monitoring is based on the principle of solid-state electrolyte, which has the characteristics of high accuracy and stability. The values of particulate matter concentration and carbon dioxide concentration are combined and output in the form of universal digital interface.
This sensor can be embedded in all kinds of instruments and apparatuses or environmental improvement equipment that are related to air quality and provide timely and accurate concentration data.
