Abstract
The purpose of this paper is to describe the development and operation of the Data Acquistion System (DAS) used for temperature collection and data analysis in a controlled-environment test unit. The DAS has a microcomputer central processing unit and specialized analog/digital temperature probes providing constant data capture. This system provides numerical and graphic outputs in both paper hard copy and instantaneous screen images. All experiments are stored on standard floppy disks for archival purposes and are easily obtained in complete form. Data analysis of each experiment is provided in graphic form with temperature in the “X” axis and time in the “Y” axis. The DAS provides a labor-free method of data gathering that can be used in a standard research laboratory or in remote settings with portable power generators.
