Honeywell’s HMC5883L 3-Axis Magnetometer can measure both the direction and the magnitude of Earth’s magnetic fields. Think of it as a Digital Compass.

HMC5883L features low-voltage operation (2.16 to 3.6V) and low-power consumption (100 μA) thus an excellent choice for battery powered applications. It has 12-bit ADC that enables 1° to 2° compass heading accuracy. The Board supports I2C (2-wire) digital interface.

Applications: These tiny sensors are used in Cell Phones to detect your heading in GPS/Maps application. Their applications include and are not limited to Auto Navigation Systems, like Unmanned Aerial Vehicles for finding the Heading and Personal Navigation Devices.

Features:

-Pull-Up Resistors can be enabled/ disabled using the Solder Jumper on the Bottom Side.
