3、long with the change of temperature, and we can read the temperature out according to the infinity. This method is not convenient, and it takes a long time to measure. This paper proposes a new thermometer project to measure the temperature signal by using the TN series infrared temperature sensor w
4、hich has the SPI (Serial Peripheral Interface). The sensor can measure both the target temperature and environment temperature at the same time, meanwhile the temperature data which have been measured can be transferred to the SPCE061A microcontroller to process. Then, the data will be transferred t
5、o data display, and will be reported by using the SPCE061As voice report function in the meanwhile. Infrared thermometer breaks through traditional temperature measurement pattern. It responses quickly, and has high accuracy and high reliability and measures in large area. It is also a way of non-co
6、ntact measurement, so it isnt easy to break. This thermometer can measure accurately and quickly, and has the clear and easy display. All these offer convenient condition to our daily life. Furthermore, the voice report function makes it more intelligent and human.
