#### Abstract

To measure of important variables such as temperature, weight, and relative humidity in food processing process, computer-aided data acquisition system was composed of 16 bit microcomputer and PCL-711S interface board. Process variables in dehydration and storage of food were measured through sensors, converters, and computer system which were operated by the PC-LabDAS software for data acquisition, process control, and data analysis. The relationship between measured values of process variables and the output voltages of ADC showed more than 0.99 in $r^2$ value. Response time of sensors was enough fast to measure minute values changed in a moment.
