Abstract :
The Core of the system is MSP430F133, which embedded 12-bit A/D converter, complete data conversion and processing, The pyroelectric infrared sensor collect temperature and the temperature compensation circuit compensate for the error, Tempreture dynamic display is carried through LED digital tube, And the operating mode is selected by Keyboard. In the system design process, we use the least square method to fit the experimental data, in order to better reduce the system error and random error.
