Carbon Dioxide Sensor
The amount of carbon dioxide in the blood can increase when we are exposed to high levels of carbon dioxide, resulting in carbon dioxide poisoning or Hypercapnia. Measuring carbon dioxide level in the air both, indoors and externally in industrial processes is important. A high level of carbon dioxide implies a lower level of oxygen in the air.
The carbon dioxide sensors carried by Sensor eStore are either Non Dispersive Infrared (NDIR) gas sensors or chemical gas sensors. The detection level ranges between 0 – 50%.
The NDIR sensors are based on measuring the infrared intensity of dual wavelengths, one absorbed by the carbon dioxide gas and other unaffected by the gas. The carbon dioxide gas concentration is determined by comparing the two detector signals.
Chemical carbon dioxide sensors use sensitive polymeric layers and the energy consumption is very low. It can be less in volume to fit into microelectronic-based systems. In comparison with the NDIR type, the overall lifetime of chemical sensors is rather low due to short- and long term drift effects.
