Abstract
A carbon dioxide sensor has a conduit connecting to a source of breathing air and delivering a sample of breathing air into a test chamber. A radiation source applies radiation across the chamber. A sensor detects modification in the radiation as it passes through the air sample in the test chamber and communicates with electronics to identify a percentage of carbon dioxide in the sample. A rigid cover surrounds the radiation source, the test chamber, and the sensor. A spacesuit is also disclosed.
