Temperature is one of the most frequently encountered parameters in production process and scientific experiments . Thus, the temperature detection and control are definitely vital in the forementioned or any other similar processions. As the basis of the temperature control ,the temperature measurement technology has now become simple and mature. In this design, AT89S51 single-chip is chosen as the center control and DS18B20 temperature sensor performs the temperature measurement with LCD1602 liquid crystal display to realize data transfer and values display.The main part of this design consists of two aspects. One of them is the design of the hardware of the system, including the temperature gathering electric circuit, the display circuit and the alarm circuit.The other aspect is the design of the software of the system, which includes the realization of the data collection and temperature display by the use of C language. Measured temperature value can be directly read through the DS18B20 and the data will be transferred into the single-chip. Afterwards, the single-chip will output and display the data. The design is able to achieve multi-point temperature acquisition, s
