Therefore, it is very important to develop a system that can accurately measure and record the value of this parameter.The temperature monitoring system of base on the ARM is use of embedded Linux as the operating system for the processor to S5PV210 development board designed for an embedded temperature monitoring system. Based on the analysis of the basic working principle based on the Linux device drivers discussed development often encounter interrupt handling, congestion handling, I / O ports, and on this basis to achieve the embedded processor based on open S5PV210 reading, writing, characters off the external RAM device driver and network drives. Combined with precision temperature sensor DS18B20, to achieve the correct temperature acquisition, and upload the data via Ethernet to a PC client.At first,the paper introduces the characteristics of various devices in a communication network, the bus structure and transmission technology, and according to the principle of serial communication between SCM and PC, with ubantu complete temperature monitoring system software design and implementation, to provide users with a friendly man-machine interface, the monitoring system to control and display the da
