| Abstract: | Based on LabVIEW and 1-wire bus, a temperature detceting network has been constituted by using digital thermometer DS18B20s and microprocessor AT89C52, which can monitor temperatures of a large quantity of positions in distributed surroundings. Alarms will send out once the temperature is out of the set range, and all of the temperature datas can be stored and printed out. All DS18B20s are connected with AT89C52 through a three-state interface, which makes the line-arrangement convenient and dependable. The login and logout on line of DS18B20s are suitable for the number and position changes of thermometers. |
