In the first part of the final paper we dealt with the measurement of the impact force with the force and the acceleration sensor. Both sensors were installed on the impact hammer at the same time. In order to obtain the impulse of the force from the measured acceleration, we had to determine the correction factor by which the acceleration should be multiplied. We tested the hammer with three impact tips of different hardnesses and calculated correction factors for each one. We have found that it differs for each tip. The second part of the paper includes the application of the MEMS accelerometer and the comparison of the signal obtained with the signal of a professional reference accelerometer. We obtained the MEMS accelerometer's signal via the Arduino platform and the professional accelerometer's signal via LabView program. We then compared the graphs of the two signals and found that an error occurs in the MEMS sensor after the acceleration has reached it's amplitude. During the course of the task, we determined the factors by which the MEMS accelerometer’s signal must be corrected to obtain the most exact impulse of the force. For all acquired signals, we also did a Fourier transformation and obtained an image in the frequency domain.
