摘　　要：磁敏传感器是利用导体、半导体的磁电效应制成的,它是一种能够将磁场信号转换为电信号的传感器。磁敏传感器的主要作用是检测磁场信号,最大的优点是无接触检测,也就是磁敏传感器与被检测物体之间不需要直接接触就能得到相应的反馈信号。简要叙述了磁敏传感器的基本内容,并基于磁敏传感器设计了一款实用性比较强的数字显示转速表——霍尔传感器。The magnetic sensor is the use of conductors, semiconductors made of magnetic effect, which is a way to convert the magnetic field signal into an electrical signal. The main role is to detect the magnetic field magnetic sensor signal, the biggest advantage is the non-contact detection, which is no direct contact between the magnetic sensor and the object to be detected can get the appropriate feedback signal. A brief description of the basic contents of magnetic sensors and magnetic sensors designed a relatively strong practicability digital tachometer display based - hall sensor.
