  • Very useable magnetometer

    posted by ggutshal on 14:25:01 G11T 07/11/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Very small form factor. I2C interface so it doe not consume too many IO pins. The HMC5883 magnetometer is a pretty standard part in the microcontroller/robotic community. Libraries exist for arduino and netduino

    Cons: math is required to use this magnetometer as a compass. Calculating headings requires some complex higher order math functions that may not exist on all platforms, forcing you to code those calculations at a much more intimate level, especially if your microcontroller does not support floating point math.

    Other: Should be very useful for robotics, unmanned aerial vehicles or other implementations requiring the detections of orientation. Alternatively this module could be used in any application that calls for a highly sensitive 3d magnetometer.
