摘要
介绍了以温度传感器TMP04为检测器件的风速传感器的测量方法。系统以单片机AT89C51为核心,由风速传感器采集数据,单片机接收并处理数据,LED数码管显示测量风速值。采用分段插值法进行非线性数据处理;描述了电路设计和软件实现。由于采用了数字温度传感器做检测器件,省去了放大电路和A/D转换器,测量电路与单片机接口简单,编程处理简单。
A detecting method of wind speed sensor is introduced;its detecting part is temperature sensor TMP04. Single chip processor AT89C51 is the core in the system. The data are gained by wind speed sensor, and single chip processor processes it. LED shows the wind speed data. The piecewise interpolation is used to do nonlinear data processing. The design of circuit and the approach of software are described. Because digital temperature sensor is used as detecting part,amplifier and A/D is omitted .The interface of measuring circuit and single chip processor is simple, the software is simple.
