Description: 温度传感器ds18b20，时钟芯片DS1302在LCD602上的显示,该系统可显示当前时间
可模拟采集湿度LCD H后面的数据代表湿度
系统可设置温度S 后面的值为设定温度
P后面为采集温度来自DS18B20温度传感器
当采集温度大于设定温度系统自动启动风扇
对恒温箱降温，当采集温度小于设定温度
系统自动启动加热电路，对系统加热。-Temperature sensor ds18b20, the clock chip DS1302 in LCD602 shows that the system can display the current time
Can simulate the humidity H at the back of the LCD data on behalf of the humidity
At the back of the system can set temperature S value is set temperature
Behind the P for collection from the DS18B20 temperature sensor
When the temperature of the acquisition is greater than the set temperature automatically start the fan
To cool incubator, when the temperature of the acquisition is less than the set temperature
System automatically start heating circuit, the heating system.
