The Compass Module is designed for low-field magnetic sensing with a digital interface and perfect to give precise heading information. This compact Sensor fits into small projects such as UAVs and robot navigation systems.
The Sensor converts any magnetic field to a differential voltage output on 3 axes. This voltage shift is the raw digital output value, which can then be used to calculate headings or sense magnetic fields coming from different directions.
