This paper describes the design and prototyping of a modular, portable, reconfigurable, and wireless multipurpose sensor system for monitoring and recording environmental conditions in aircraft cabins. The objective of this small, portable embedded sensing system is to record aircraft cabin conditions on flights of convenience to generate a large database for determination of normal conditions. By designing a sensor system that can be easily reconfigured for different needs (with the ability and flexibility to accommodate different/extra sensors), the system can be used to measure parameters that meet multiple research requirements.
