摘　　要：讨论了一种利用气压来测量高度的方法。该方法利用微型数字压力传感器SCP1000-D01得到数字压力信号,再通过ATMEL公司的8位微处理器Atm ega 16L读取压力信号并对其进行处理,利用气压、温度和海拔高度之间的关系,用软件实现高度值的计算,并在液晶显示屏上显示气压和高度的具体数值。The circuit design and algorithm research of a barometric leveling system were discussed, which uses micro digital pressure sensor SCP1000 - D01 to get the digital signals. Microcontroller chip AVR, an 8 bit micro - controller produced by ATMEL, was used to read the signals and process them. The height calculation was conducted by applying the relationship between the pressure, temperature, and altitude. Then the result of the pressure and altitude on the LCD was displayed.
