1. A carbon dioxide sensor comprising:
- a conduit connecting to a source of breathing air and delivering a sample of breathing air into a test chamber;
a radiation source for applying radiation across said chamber and a sensor for detecting modification in the radiation as it passes through the air sample in the test chamber and communicating with electronics to identify a percentage of carbon dioxide in the sample; and
a rigid cover surrounding said radiation source, said test chamber, and said sensor; and
wherein said cover has a first portion surrounding said radiation source, said test chamber and said sensor, and a second portion that encloses a connection point for said conduit to be connected to the source of breathing air.

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.

8. A spacesuit comprising:
-
a suit; a source of breathing air and a conduit delivering a sample of the breathing air into a test chamber of a CO2 sensor; said CO2 sensor being within said suit, said CO2 sensor also including a radiation source for applying radiation across said chamber and a sensor for detecting modification in the radiation as it passes through the air sample in the test chamber and communicating with electronics to identify a particular percentage of carbon dioxide in the sample; a rigid cover surrounding said radiation source, said test chamber, and said sensor; wherein there is a port adjacent to said carbon dioxide sensor for expelling fluid from within said spacesuit; and wherein said port has a hydraulic diameter, and a distance between an outer edge of said port, and a closest portion of said carbon dioxide sensor is less than said hydraulic diameter. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
