摘　　要：采用MS5534B,利用海拔高度与气压和温度的关系,设计并制作了微型气压高度计。通过数字压力传感器和ATMEL公司的ATmega16L单片机进行串行通信,读取传感器中压力、温度值及补偿参数,用软件进行温度补偿和高度计算,并能在液晶屏上显示具体数值。设计的气压高度计样机具有质量小、功耗低、精度高、工作可靠等优点。According to the relationship among pressure, temperature and altitude, an altimeter system with MS5534B is designed. Using digital pressure sensor and microeontroller chip ATmega16L of ATMEL company to make serial communication ,the pressure ,temperature and compensation parameters from the sensor are read out. Compensation of temperature and calculation of height are carried out with the software,the data which have been processed to the LCD can also be transferred. And the altimeter has many merits such as light weight,low power consumption ,high precision and high reliability etc.
