Abstract:

A hardware circuit for the measurement of thermistor characteristic curve and a lowcost lockinamplifier (LIA) based on virtual instrument is successfully designed. Then the measurement system of the thermistor property curve based on computer remote control is developed. The result of remote experiment based on virtual instrument is consistent with the experiment of traditional laboratory.

Key words: thermistor, virtual instrument, remote control, LabVIEW
