Application Report SLIA086 July 2014 1 Understanding & Applying hall Effect Sensor Datasheets Ross Eisenbeis Motor Drive Business Unit ABSTRACT hall Effect sensors measure magnetic fields, and their datasheet parameters can initially be difficult to understand and apply toward system design. This article provides a baseline of information. Units A magnet produces a magnetic field that travels from the North pole to the South pole. The total amount of field through a 2-dimensional slice is the flux , in units of weber. Webers per square meter describes flux density, in units of tesla (T). The unit of gauss (G) also describes flux density, where 1 T = 10000 G. In millitesla, 1 mT = 10 G. Tesla is the official SI unit, and it s used by TI datasheets, but many other sources use gauss.
