Compass Module 3-Axis HMC5883L

The Compass Module is designed for low-field magnetic sensing with a digital interface. Perfect to give percise 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. Example code in PBASIC, Spin, and C are provided in the downloads.
