The GY-273 module is based on the Honeywell HMC5883L integrated circuit for low-field magnetic detection with a digital interface for applications such as low-cost compass and magnetometry. The HMC5883L uses Honeywell's isotropic isotropic AMR (Magneto Resistive) technology from Honeywell, which offers advantages over other magnetic sensor technologies. These anisotropic directional sensors offer a sensitivity and a linearity of precision in the axis.
