Application of Silicon Piezoresistive Transducer and AD7705 in Pressure Measuring System

In this paper,a new type sensor based piezoresistive effect and its working principle are introduced,and an example of MPX2100 is illustrated.Combined with IC AD7705,a pressure measuring system is made.Design method of software and hardware is given for the microcomputer measuring system and piezoresistive transducer of MPX2100.
