模拟“温度采集与控制装置”用于实现温度的实时监测与控制。单片机采集 DS18B20 温度传
感器的输出信号，并送到数码管进行显示；通过传感器得到的温度数据将与用户设定温度上限、下
限值做比较，再由单片机启动控制或报警电路。系统硬件部分主要由单片机最小系统、数码管显示、
DS18B20 温度传感器、矩阵键盘等模块组成。(Analog "Temperature collection and control device" is used to realize real-time monitoring and control of temperature. The single chip computer collects the output signal of the sensor temperature sensor and sends it to the digital tube for display, and the temperature data obtained by the sensor will be compared with the user setting the temperature upper limit and the lower limit value, and then the control or the alarm circuit should be started by the MCU. The hardware of the system is mainly composed of single-chip microcomputer minimum system, digital tube display, sensor temperature sensor, matrix keyboard and other modules.)
