Digital demonstration type
electron clinical thermometer's design
Abstract: Temperature is a manifestation of life. It is an important human physiological metabolic parameters, body temperature of both the significance of physiology, and important clinical significance, clinical diagnosis is an important indicator. Therefore, the thermometer in life now there is a very important role, the traditional mercury thermometer easily broken, there is the possibility of mercury pollution, a longer measurement time, it is not easy reading, for the design of a new type of electronic thermometer, and its temperature measurement accuracy with the traditional comparable to the mercury thermometer, the temperature greatly reduces the time and easy to carry, almost no pollution on the environment. AT89S52 its single-chip microcomputer as the core, combination of temperature sensor, LED modules and other external equipment, under the control of the software, the realization of intelligent temperature measurement, temperature measurement can not only accurate, but the logic can determine the temperature and the adoption of LED displays the measurement results will be displayed.
Key word: Electronic clinical thermometer ；Intelligent temperature sensor； Monolithic integrated circuit
