Design of Water Bath Temperature Control System Based on DS18B20* Zhiyong Zhang1, a, TieLiang Guo2,b 1College of Electric & Information Engineering, Heilongjiang Institute of Science &Technology, Harbin, Heilongjiang, China 2Dept. of Science, Heilongjiang Institute of Science &Technology, Harbin, Heilongjiang, China azhangzhiyonging @163.com, bgotlang@163.com Keywords: DS18B20; AT89C51; Water Bath Temperature Control Abstract.
Water (or electrolyte solution) temperature changes in the range of most physical chemistry and biochemistry reaction temperature, and water is a kind of low cost material that has larger heat capacity, so water has become the preferred medium to transfer heat in those applications.
*Granted by Scientific Research Fund of Heilongjiang Institute of Science &Technology (NO.08-09) Conclusions DS18B20 can improve the accuracy of the water bath temperature control system.

Another problem is that friction wheel maybe soon wear out, so appropriate material should be select.
Summary With the development of science and technology, mechanical products is becoming more complex, designing simple and effective mechanism scheme to satisfy given function requirements of mechanical products is becoming increasingly important.
