【Abstract】 This article has designed the AVR microcontroller ATmega16 as the control core, with single bus digital temperature sensor DS18B20,photocell sensor 2DU6,pressure sensor MPX2050 and acceleration sensor ADXL202 acting as main parts of the portable vital signs dynamic monitor system. The system overall design as well as hardware and software design of each module are given. The function of collecting and recording signals, LCD display and alarm prompt can be realized through the software programming and simulation. The monitor system has merits of simple to operation, low power loss, humanization and easy to take with etc.更多还原
