根据两路模拟电压信号控制输出电压模拟信号(According to the two analog voltage signal control the output voltage analog signal)

读取DS18B20进行温度测量以后的结果并在1602液晶上显示。 基于DS18B20的温度控制器。温度控制范围在20~30℃，当温度大于30度时，停止加热，小风扇通电开始降温，绿灯亮。温度低于20度时，小风扇停止通电，开始加热。红灯亮。全过程有LCD数字温度显示。(Read DS18B20 temperature measurement after the results of the 1602 LCD display. Based on DS18B20 temperature controller. Temperature control range of 20 to 30 ℃, when the temperature is greater than 30 degrees, stop heating, small fan is energized to start cooling the green light. When the temperature is below 20 degrees, a small fan is stopped is energized, the heating is started. Red light. The whole process of LCD digital temperature display.)
