Volume third, phase second, September 62010 Journal of Cangzhou Teachers College, Journal, of, Cangzhou, Teachers, College Vol. 26, No. 3, Sep.2010 Design of temperature and humidity acquisition system based on DS18B20 Chai Suozhu, 1, Jin Jing, 2 (1. 、 School of computer and software, Nanjing Institute of Industry Technology, Jiangsu 246, Nanjing 1002., Cangzhou Normal University, Hebei 061, Cangzhou, 100); Department of physics and electronic information Abstract: in view of the current temperature and humidity acquisition system requirements, the design of a single bus digital temperature sensor DS18B20 and STC90C52AD microcontroller composed of a new temperature and humidity collection system. This paper introduces the structure and working principle of the main device, and gives the hardware design and software flow chart of the system. The system has the advantages of accurate data acquisition, low power consumption, convenient communication with the host computer and so on. Key words: DS18B20; STC90C52AD; data acquisition; communication graph number: TP368. 2; document identification code: A; Article Number: 1008-4762 (2010) 03- 0104- 02 DS18B20 can use external power supply or parasitic power supply mode. The parasitic power supply mode is 1- Wire bus device, which can obtain power from the data wire, so that the power line can be omitted, and the power supply and data transmission can be realized by using two wires. Since each 1- Wire bus device has a unique 64 bit serial number as the identifier (address), the host can search all devices connected to the bus and access and control each device on the bus. The direct measurement of the temperature sensor will be converted to dig
