2018-02-21 Comparison of FG-3+ fluxgate sensor data to USGS fluxgate data from BSL
The E-W geomagnetic field was measured using a FG-3+ fluxgate sensor. The FG-3+ sensor output frequency is proportional to magnetic flux density. The frequency change in the plot corresponds to about 2nT. The sensor output frequency was measured directly with an Arduino Uno R3. Bottom plot is data from USGS BSL station (NASA Stennis Space Center, MS).
