Abstract
The titl angle measurement system based on the ADXL345 of three-axis acceleration sensor is introduced ,and the composition and working principle of the system are described .The MSP430F149 microcontroller of ultra-low power and high performance is adopted .Firstly ,the voltage value which is proportional to the acceleration value is output by ADXL345 when the system is powered .Secondly ,the voltage value is converted into the corresponding digital signal by AD converter of the sensor .Thirdly , the digital signal is transformed into the titl angle according to the arithmetic processing of the MSP430F149 .Finally ,the corresponding angle is displayed on the liquid crystal display (LCD) screen .Experimental results show that the design has high sensitivity and response speed compared with the conventional methods .It is suitable for prac-tical engineering application because of simple structure ,low cost and low power consumption .关键词
