This paper introduces the design of soil matrix intelligent inclinometer based on MSP430 microcontroller.The design of soil matrix displacement measurement system used MSP430F148 as core components,combined with accelerometer sensor and expanded the certain peripheral circuit.The system used the timer and A/D module of signal-chip to control the sampling frequency and analog-digital conversion,not only made full use of CPU,but also reduced the design of external circuit.The lower computer programmed the signal collection,A/D conversion and UART.And the upper computer programmed with Delphi language,to achieved displacement of soil-based data collection,processing,printing and other functions.The results show that the system precision is 0.01°,the minimum resolution is 1.5″(±15°),and the minimum displacement is ±0.01mm.
