Carbon Dioxide Detection Alarm

Carbon dioxide detection alarms use infrared sensors to absorb specific wavelengths of infrared light, detecting changes in gas concentration by measuring variations in electrical signal strength. They are used to monitor carbon dioxide levels in enclosed spaces, such as fermentation workshops and greenhouses, to indicate the need for ventilation.
Selection
When selecting, focus on a detection range covering 0–5000 ppm with a resolution of 1 ppm. Consider diffusion-type or pump-suction sampling methods, equipped with audible and visual alarm functions. Check the sensor lifespan and calibration cycle, ensuring compatibility with temperature and humidity environmental requirements.
