本系统可以实现多路温度信号采集与显示，可以使用按键来设置温度限定值，通过进行温度数据的运算处理，发出控制信号达到控制蜂鸣器和继电器的目的。
The system achieves multi-channel temperature signal acquisition and control. Temperature limit is set by keyboard. The buzzer and relay are controlled by MCU.
在这里你可以找到一段关于如何启动马达、校准(蜂鸣器发出1声确认设置1)和关闭马达的视频演示。
Here you will find a video demo of how to start the motors, calibrate (1 beep confirms setting1), and stop the motors.
当超声波模块与障碍物之间的距离超过设置的上限值或者下限值时，蜂鸣器发出报警。
When the ultrasonic distance between the module and the obstacle exceeds the upper limit or lower limit, the buzzer alarm.
比较功能，上下限偏差值自由设定，红绿指示灯及蜂鸣器自动声光报警设置；
Compare function, free to set upper and lower deviation, red and green indicator light and buzzer sound and light alarm settings automatically;
还能够设置温度预警值，当采集到地温度超越设置地预警值时，驱动蜂鸣器报警。
Can also set the warning temperature value, when the acquired temperature exceeds the warning set value, the drive buzzer alarm.
