Reliability of the 3-Axis Digital Compass HMC5883L

The 3-Axis Digital Compass HMC5883L sensor is able to acquire information even in a low magnetic field. Distributed over the three axes, this information is converted into a differential voltage of 2.7 to 6.5 VDC to provide input for a vast range of microcontrollers operating at different voltages.

The raw digital output value can be used to calculate direction and location, and for measuring both the magnitude and the direction of the Earth’s magnetic field in cases where the robot needs to measure several magnetic fields coming from different directions.

For what type of project could the HMC5883L compass be chosen for?

The Parallax compass’ configuration and digital interface make it ideal for integrating into a drone or the navigation system of a mobile robot both of which may be small. It can be easily programmed in PBASIC, Spin or C (examples are available for download).
