Intended Electromagnetic Interference with Motion Detectors

Electromagnetic Interference with sensors has led to various problems in the past. In this work, two sensors, a gyroscope and an accelerometer are examined with respect to their susceptibility to interference. These sensors can be found in various electronic systems like drones, mobile phones, cars, etc.. The sensors are placed in a TEM cell and a signal generator excites a sine signal with the frequency between 5MHz and 1GHz. It is shown how susceptible to electrical fields the sensor system is. Finally, the analysis of the communication between the sensor and a controller over an I2C bus shows how simple it is to disturb a sensor system.
