This method is composed of the fire detector， monitoring terminal and wireless communication system. The temperature sensor and meteorological sensor in fire detector are used to acquire the fire data， and then the ZigBee wireless sensor network （WSN） is used to feed the fire data back to the monitoring terminal to accomplish the fire detection. The fire detector includes the array sensor module， information management module and ZigBee wireless communication module， which can realize the acquisition， analysis and transmission of fire data. In the process of software design， the code of temperature and humidity acquisition program is given， and the fire location method based on wireless sensor network is analyzed. The fire source position can be located accurately. The experimental results indicate that the method can detect the temperature， humidity and smoke information accurately， and realize the accurate fire positioning. 　　Keywords： wireless sensor； ZigBee； fire detector； fire positioning 　　火情隐患突发性强，由于传统的火情监控体系无法准确定位燃火点，因此消防员并没
