Lightweight, Compact Atmospheric Gas Sensor

SRD will develop a miniaturized atmospheric gas sensor array and design a gas analyzer (sensor analyzer module, SAM) capable of accurately detecting and autonomously monitoring critical atmospheric gases in enclosed spaces. In this Phase I effort, SRD will use its current, existing technology (miniaturized sensor platform, proprietary SMO sensor coatings and advanced signal processing algorithms) and make appropriate engineering modifications to meet the environmental background challenges specified by the solicitation. O2, CO2, CO and TCA will be detected and identified in real-time, in a continuous monitoring mode at pressures ranging from 1 to 6 ATM, temperatures of 32 to 105 degrees F, and a wide range of humidity. The low power requirement of the sensor array and supporting electronics will lead to rapid development of a lightweight, portable, waterproof atmospheric SAM, suitable for environmental monitoring and atmospheric control applications aboard small submersible vessels, within piping systems or adapted for use in atmospheric monitoring and control of UBAs. The portable gas analyzer will be used as an autonomous real-time gas monitor with the option of linking multiple analyzers together with wireless communication to create a distributed environmental gas monitoring network.
