ACD3100 CO2 Sensor Module Infrared NDIR CO2 Gas Concentration Detection For Air Quality Monitoring

ACD3100 CO2 Sensor Module Infrared NDIR CO2 Gas Concentration Detection For Air Quality Monitoring

• Principle: ACD3100 is based on the non - dispersive infrared (NDIR) principle to detect the carbon dioxide concentration in the air. It is designed based on the spectral absorption principle of CO₂ gas. The sensor consists of three parts: a light source, a gas chamber, and an infrared receiver. When CO₂ flows into the gas chamber through the gas inlet and out through the gas outlet, it will absorb infrared light of a specific wavelength in the gas chamber. The change in CO₂ concentration will affect the infrared absorption amount, and then the infrared receiver will receive a light source signal of different intensities. The sensor calculates the CO₂ concentration by detecting the absorbance of infrared light of a specific wavelength.
• Features: It has excellent selectivity, no oxygen dependence, and a long - service life. It integrates integrated infrared absorption gas detection technology, a precise optical path design, and a high - precision dual - channel signal detection circuit to ensure the accuracy and reliability of the measurement results. In addition, it is equipped with a digital interface output, which provides users with a convenient data reading and interaction experience.
• Applications: It is widely used in many fields such as air quality monitoring, fresh - air systems, air - purification equipment, and HVAC equipment.
