• Magnetometer HMC5883L is used for measuring the direction and magnitude of the Earth’s magnetic field. It 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 to find the direction of heading of the device. • It uses I2C protocol for communication with microcontroller.

Specifications:

• I2C interface. This board/chip uses I2C 7-bit addresses 0x3C • 1-2 degree heading accuracy • Integrated 12-bit ADC • 160Hz max data rate • Range of -8 to 8 Gauss
