HMC5883L Magnetometer Sensor

OVERVIEW:

Magnetometer HMC5883L measures the direction and magnitude of the Earth’s magnetic field and hence is used for low cost compassing and magnetometry.

It measures the Earth’s magnetic field value along the X, Y and Z axes from milli-gauss to 8 gauss.

It can be used as a compass to find direction or to find the direction of the heading of a device.

It makes use of I2C protocol for communication with a microcontroller. Earth’s magnetic field values along the X, Y and Z axes can be found by reading values from addresses of certain registers using I2C communication.

Features:

• I2C interface
• 1-2 degree heading accuracy
• Integrated 12-bit ADC
• 160Hz max data rate
• Range of -8 to +8 Gauss
