智能温度控制器

代码说明：

  当温控开关打开时，若测得环境温度大于设定温度，则继电器吸合 启动电机工作；若测得环境温度小于设定温度，则继电器释放， 电机停止工作；(When the temperature control switch is turned on, if the measured ambient temperature is higher than the set temperature, the relay will suck in. Start the motor; if the measured ambient temperature is less than the set temperature, the relay will be released. The motor stopped working.)
