Match with the infrared ray long-distance technology, it realizes near-distance control and uses the single-total line digital temperature Spread the feeling machine DS18B20 and high accuracy clock calendar chip PCF8560 to manifest the clock 、the calendar and the temperate. The main control part of this system is made up with the MCU, it does the main massage handles, receives exterior operation instruction and forms various control signal. In the aspects of long-distance controlling , using different voice to hint different operation and give a state feedback of the be-controlled ,thus it can let the writer know the information of the be-controlled, let the production to be change over with each other type and intellectualized。The auto dialing alarming function made up with the phone improves the usage of this system highly, makes the family life more intellectu- alized.Connecting this system with the PC and using the appliated program, it can control the household appliance by the PC machine directly. The PC machine can be hand-controlled and also can be controlled by the infrared ray remote control. It has many superiority on it. For example, agi
