Abstract: The system of design integrated electronic technology theory, from the actual conditions of life, improving the function of the drinking fountains. The Design project with the main use of AD590 and phototransistor as a test unit has still used the MC14433, 74LS160, such as integrated device. The whole design system tries to achieve two functions, namely, digital temperature measurement and automatic control of the number of heating, including detection, A / D converter (Count), decoding strobe, relay control such circuit modules. Compared with the traditional drinking fountains, the use of automatic detection and control of electronic design technology, can better achieve the right temperature and water quality measurement and control, with a wider range of applications.
Keywords: Detection Unit，Temperature Sensor AD590，Automatic Control，Relay
