本设计主要是由两个模块组成来实现本设计的目的－－测速模块和测温模块。测温模块由温度传感器直接将测到的温度数据（数字信号）传给单片机进行处理，最后显示在LED数码显示管上，主要的难点在编程上，如果编程将传感传来的温度信号转换为单片机可处理的信号，最后显示在LED数码显示管上-This design mainly consists of two modules to achieve the designed purpose- speed module and the temperature module. Temperature measurement module temperature sensor directly from the measured temperature data (digital signal) to the microcontroller for processing, and finally displayed on the LED digital display tube, the main difficulty in the programming, if the programmed temperature of the sensor signals coming signal for the microcontroller can handle, and finally displayed on the LED digital display tube
