LED-Based Low Cost Gas Sensor for Crew and Vehicle Safety

CO/CO2 measurements are relevant to the health and safety of the crew. CO is toxic, even in concentrations as low as 50ppm. Time-resolved measurements of CO can be used as early indicator of fires. CO2 concentrations must be monitored in crew cabin for safety. With compact, low-cost, low-power sensors that are able to continually monitor important gases that are characteristic of burning materials, a distributed sensor array could be implemented on space vehicles that would allow early detection of fires, gas leaks, or other critical events. With careful selection of targeted gases it may be possible to identify the material that is burning/smoldering which will better inform the crew so that they may respond and prioritize high emergency events. Current sensor design targets CO/CO2 which are traces gases that increase in the presence of smoldering/burning materials. Future iteration will extend to target additional gases such as HCN, hydrocarbons, and polymer vapors.
