The lemperature dala are collected by dig ital temperature sensor DS I8B20, and proces sed by controlling sy st em, then show n on LCD in t ime. When the temperature is beyond permitted value, the system will so und t he alarm and send it to supervising center t hrough w ireless teleco mmunicatio n module, so t he persons in charge of the center can take m easures in time. Wit h better ability to resist inference, the system is suita ble to measure field t em perature under severe condition Key words: monitoring temperat ure; DS 18B20; GPRS; MCU o1994-2011ChinaAcademicJOurnalElectronicPublishingHouse.Allrightsreservedhttp://www.cnki.net
