Limits of vibration levels are defined in peak particle speed (PPV) format, however there are difficulties in measuring PPV due to the lack of equipment. Thus, the present work seeks to develop a specific vibration measurement equipment for the driving and pile driving process. 03 works with different deep foundation solutions were selected to measure the generated vibration. Previous tests with the cell phone were performed using an App called Accelerometer Analyzer, where the measurements were compared with the results obtained in the measurement made with a geophone. In the data analysis, a compatibility between the peak particle speeds was verified, which allowed the development of a specific application for the measurement of the vibration generated in the driving and execution of piles. New tests will be carried out to analyze the factors that cause errors in measurements with the cell phone and to develop measures to mitigate failures.
