Testrigg för marksensor

Sammanfattning: Lansen Technology is a security company from Halmstad, Sweden and their focus in developing and selling alarm solutions. One of their latest inventions is a vibration sensor that recognizes very small movements in the ground. The thesis work was made in cooperation with Lansen Technology AB and the task was to invent a test equipment that decides whether the sensor is working correctly. By generating certain frequencies with specific amplitude, we will expect the sensor to give a similar output. The final report includes all the parts of our work as studying, choosing components, programming, construction, results and conclusion.
