The Design of Digital Thermometer Based on Single Chip Microcomputer
Abstract: With the development of science and technology, parameters of temperature usually need to measure. This paper introduces design of basic method and measuring principle of the thermometer, its components include AT89C52 single chip computer, temperature sensor DS18B20, button scanning circuit, display circuit and alarm circuit. It can measure temperature in time and set the scope of temperature, and finish to measure temperature automatically. According to our test, the design are convenient and practical, simple operation, and greatly improving all kinds of technical indicators of controlled object.
