NetPicoMAG: a low-cost fluxgate magnetometer for teaching and research
MetadataShow full item record
Abstract of paper/presentation: netPicoMAG is a compact, low cost, networked fluxgate magnetometer. It is capable of detecting magnetic field vectors at 1 nanotesla, 1 sample per second resolution, and transmits real-time telemetry over the Internet. It is easy to install and requires zero maintenance. Its low cost and ease of install makes it ideal for teaching interactions between the earth's magnetic field and the aurora (solar terrestrial geomagnetism), as well as deployment in large (dense) magnetic sensor arrays.
