The GY-273 Triple Axis Magnetometer module is made using Honeywell HMC5883L, an IC for low magnetic field sensing. It is able to measure magnetic fields ranging from 1.3 ~ 8 gauss and provides I2C digital interface for applications such as low cost magnetometry and compassing. This module can easily be interfaced with Arduino Boards, Raspberry Pi, 3.3V and 5V microcontrollers as it can work from 3V to 5V supply.
