Abstract
Trace gas monitoring system inside the crew cabin of manned space shuttle requires high precision sensor instrumentation with quick response, smaller mass, compact and less power consumption. Trace gases like Carbon dioxide and carbon monoxide are the primary gases whose concentration required to be measure precisely and continuously inside the crew cabin to mitigate hazardous accidental events to occur. Conventional chemical reaction based or mass spectrometer based instruments for monitoring these gases are either bulky or relatively slower in response. Compared to that, Non Dispersive Infrared sensor (NDIR) technique is accurate, quick in response and compact. This paper covers design and realization of indigenously developed proto model Carbon Dioxide sensor based on NDIR technique. Developed sensor has resolution of better than 1ppm with measurement range from 0 to 5% Vol.
