Wireless sensor work is constituted by a group of sensors to the Ad Hoc mode wireless work, and its purpose is to coordinate perception, acquisition and processing of the geographical area covered by the workaware object, and issued to the observer. With the rapid development of munication technology, embedded puting and sensor technology and increasingly sophisticated, with perception, puting power and munication capabilities of the tiny sensors worldwide, aroused by these miniature sensors, sensor works of great concern. This wireless sensor work integrated sensor technology, MEMS technology, distributed information processing and work munication technology, able to coordinate a variety of environmental monitoring object information in realtime monitoring, sensing and collecting work distribution area, and these information processing. In the process of information collection and processing related to a platformbased system embedded systemsoriented onchip design, microelectromechanical systems (MEMS)based sensor development for distributed systems, data mining and queue data processing and adaptive working and routing wireless work protocols and security issues. It is the continuous exploration of these topics, contributed to the generation of the various branches of the wireless sensor work, as well as the development of standards. This article is to design a wireless sensor workbased temperature monitoring system, including the design of the temperature of the collection, wireless transmitter, wireless receiver, alarm and other content can be widely used in industrial monitoring, smart buildings, environmental monitoring field Keyword： Wireless sensor
