      Commercial Carbon Dioxide (CO2) Sensor YY-MSGA-CO2

      The YY-MSGA-CO2 Commercial Carbon Dioxide (CO2) sensor is a single channel,non-dispersive infrared(NDIR) sensor.Within the YY-MSGA-CO2 is a sensing chamber with an infrared source at one end and a
      detector ftted with an optical filter at the other end.The inner wall of the sensing chamber treated with a special process can effectively improve the efficiency of light emission, use the principle of mirror reflection to effectively increase the optical path, and improve the sensitivity and accuracy of the sensor.The source emits radiation at wavelengths which include the absorption band of CO2.The filter blocks wavelengths which are not sensitive to the presence of CO2, thereby increasing selectivity and sensitivity.As the light passes through the sensing chamber, a fraction is absorbed if CO2 is present. The thermopile detector integrates a 1000 times amplifier (AFE). AFE has a good noise suppression function,which can effectively suppress external electrical noise interference. The signal received by the detector has a large output after 1000 times amplification, which can effectively improve the sensitivity and accuracy of the product .The Automatic Baseline Correction (ABC) function can automatically calibrate the sensor's lowest reading over a pre-configured interval to 400 ppm CO2. This enhances long term stability and may eliminate the need for calibration.
