GY-273 HMC5883L Triple Axis Compass Magnetometer Sensor Module
GY-273 is a 3-axis magnetic compass that is used to measure the magnetization of various magnetic materials.
It can also be used to measure the intensity of a magnetic field.
This module converts any said magnetic field into a voltage output on 3-axis.
This voltage shift is the raw digital output value, which is then reverse-engineered to calculate the values of magnetic fields coming from different directions.
Magnetometer GY-273 measures the orientation and magnitude of the Earth’s magnetic field and hence is used for low-cost compassing and magnetometry.
Earth’s magnetic fields along the X, Y, Z-axis can be found using this sensor.
This module uses an I2C communication interface.
