In this paper, microcomputer with the sensor technology development and design of the temperature monitoring system. Paper sensor combination of the practical application of theory of SCM in detail about the use of thermistor temperature as a thermal sensor to detect the process, and the realization of the principle of thermoelectric conversion process. Circuit and software design, use of software systems Protel99 circuit schematic for the design and build the circuit boards. Function of each part of the article, realize the process in detail. The core of the system for temperature monitoring. Sensors of various physical quantities can, chemical content and biomass signals into electrical signals so that people can use computers for automatic measurement, information processing and automatic control, but they have varying degrees of the influencing factors such as temperature drift and nonlinearity .Sensors are used to measure and control system, its performance directly affects the system performance. Therefore, not only to master the structure of various types of sensors, theory and performance, but also must understand the sensor interface circuit through the appropriate adjustments to meet the signal processing, display an
