You only need external power supply and clock then the digital information processing and control can be achieved on. Because of the small scale, low price and high efficiency of MCU, it is widely used in home appliances and industrial control. Multichannel temperature acquisition system is used temperature thermometer DS18B20 to detect the temperature, process and display by the singlechip. This design uses AT89S52 as microprocessor to realize design goal this design including temperature gathering circuit, keyboard circuit, display circuit, alarm circuit etc. to achieve the temperature detection and the display. To introduce the problems during the debugging are analyzed and summarized, some measure about the system improvement are proposed. The result of experiments indicated that signal sampling system has good performance, high precision, and has a very high pertormancetoprice ration.
