Abstract : A computer based, multichannel physiological temperature monitoring system is described. Thermistor probes are used as temperature transducers. A constant current thermistor driver converts the resistance of the thermistor probe to a temperature dependent voltage. This voltage is digitized by a multichannel analog to digital converter on command of a small computer. The computer controls the rate of data collection, stores the data, and performs the necessary algebraic manipulations to convert the data to a tabular or graphic temperature display. System operation, including thermistor calibration, data collection, and data reduction is discussed. Flow charts of representative software and schematics of hardware are included.
