Citizen science: Development of a low-cost magnetometer system for a coordinated space weather monitoring.

As part of Ham Radio Science Citizen Investigation (HamSCI) Personal Space Weather Station (PSWS) project, a low-cost, commercial off-the-shelf magnetometer has been developed to provide quantitative and qualitative measurements of the geospace environment from the ground for both scientific and operational purposes at a cost that will allow for crowd-sourced data contributions. The PSWS magnetometers employ a magneto-inductive sensor technology to record three-axis magnetic field variations with a field resolution of 3 nT at a 1 Hz sample rate. The measurement range of the sensor is nT) and is valid over a temperature range of -40 °C to +85 °C.
