As everyone knows, the ambient temperature is suitable for biological can be an important factor for survival, and the perception of the environment temperature is from the pure physical senses to the development of various thermometers for accurate measurement of environmental temperature. But limited to technical reasons, the thermometer is usually larger, not higher precision of various defects. In China, because the SCM has strong function, small size, good reliability, and low price advantage， Therefore, in many aspects of intelligent instruments, industrial automatic control, puter intelligent terminal, household appliances, toys, have got very good application, and is paid more attention by people, made a series of achievements in scientific research, bee the ideal model technology to transform traditional industries and upgrade of new products, has broad prospects for development the. In modern society, the temperature control is not only used in factory production, its action also reflected in all aspects, with i
