本系统是基于STM32F103RBT6微控制器所设计的温度测量系统，通过温度芯片传感器 DS18B20 测量温度，微控制器驱动液晶模块显示当前测得的温度。该测温系统应用测温传感器DS18B20.通过DS18B20把温度值转换成数字量，把数字量送给微处理器，并在液晶显示器上显示出来(This system is based on the temperature measurement system designed by the STM32F103RBT6 micro controller. The temperature is measured by the temperature chip sensor DS18B20, and the micro controller drives the liquid crystal module to display the current temperature. The temperature measurement sensor DS18B20. converts the temperature value into the digital quantity by DS18B20 and sends the digital to the microprocessor and displays it on the liquid crystal display.)
