摘要
介绍一种基于单片机AT89C51和V/F转换器LM331的压力数据采集系统,该系统以AT89C51单片机为核心,实时测量由压力传感器MPXV5004G检测的压力。与传统电路设计相比较,其外部硬件电路少,结构简单,无较大的时延。只要对其功能进行扩展,能够实现相应控制。
A the pressure data acquistion system based on AT89C51 MCU and LM331 V/F converter is introduced.The system uses AT89C51 MCU.as a core.The system real-time measures the pressure which is deteded by pressure sensor MPXV5004G.Compared with the traditional circuit,it has less external hardware circuit,simple structure and less time delay. Processing speed is fast with the high stability.As long as expanding the funtions of the system,it controls the object timely.
