Research of Temperature Measuring Virtual Instrument Based on Smart Mobile Phone

A temperature measuring virtual instrument based on smart mobile phone is introduced in this paper. The research was mainly done about the mobile phone hardware platform combined with general purpose software developing tools to be used as virtual instrument for data acquisition and signal process. This novel idea was realized on the smart mobile phone of Nokia N91 used for temperature measuring. The experiment shows that it is very portable and with high precision, and also provide a reference method for similar instrument development.
