粮仓温度控制系统系统由单片机、数字温度传感器、液晶显示模块、键盘设置模块和报警模块组成。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，把数字量送给单片机，并在液晶显示器上显示出来。通过键盘设置温度报警上下限，可以对系统状态进行监控。通过多个DS18B20并联在一起，可以解决粮仓内多点温度分布测量问题。-Warehouse Temperature Control system consists of microcontroller, digital temperature sensor, liquid crystal display module, keyboard, set the module and the alarm module. The application of temperature sensors temperature measurement system DS18B20, through DS18B20 the temperature into a digital number, to send digital microcontroller and displayed on the LCD monitor. Temperature alarm on the keyboard to set lower limits, you can monitor the status of the system. Parallel through multiple DS18B20 together, can solve the multi-point temperature distribution inside the granary measurement problems.
