Title:

Development of a Low-Cost Ground Magnetometer Station

Magnetometer stations are a vital piece of measuring equipment that can be used to measure geomagnetic subs storms, which have significant impacts on electrical systems depending on severity. Changes in Earth's magnetic field causes currents to be induced in electrical systems. These currents can cause massive system failures in areas like such as the power grid. Currently there are very few stations, and these stations are expensive, high maintenance, and sparsely located. The aim for this project to develop a low-cost solution that can measure these changes brought on by geomagnetic substorms. One part of the project dealt with developing an alternative charging system for the battery. The previous solar based charging system could not reliably charge the battery, so an alternative to this was implemented using an additional wind-based generation system. After testing, it was decided to increase the turbines wattage due to insufficient power at low speeds or combine solar with wind. The other half of the project dealt with signal capturing. Analog and Digital filtering techniques were implemented to allow for the recording of a clean signal. Previous iterations of the system had noise issues, and the work done was aimed at resolving these issues.
