Lansen Technology is a security company from Halmstad, Sweden and their focus indeveloping and selling alarm solutions. One of their latest inventions is a vibration sensor thatrecognizes very small movements in the ground.The thesis work was made in cooperation with Lansen Technology AB and the task was toinvent a test equipment that decides whether the sensor is working correctly. By generatingcertain 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..
