In this paper the design and wireless temperature measurement and control system. This design is the Atmel company AT89S52 SCM as control core, offered to single bus chip DS18B20 distributed temperature gathering and control system. Multiple temperature sensor nodes connected through a single bus and single chip formed a distributed system. Controller through the temperature sensor real-time detection of each node temperature change, and in 12864 the LCD screen circulation shows every node temperature changes. Through a serial port will detect temperature information feedback to the PC (PC), so as to realize the remote to t
