| Abstract: | The characters and operational principles of I-wire digital temperature sensor DS18B20 were introduced, and a temperature measurement network under VC environment making use of DS18B20 and PC s parallel port was also described. The network which was composed of I-wire DS18B20 possessed some advantages such as resisting interference, convenient and easily being maintained. The results showed that the anticipated aim was basically achieved. |
