GY-273 HMC5883L Magnetometer Compass Sensor

The GY - 273 (GY273 GY 273) module is based on the Honeywell ( HMC 5883L IC ) for low-field magnetic sensing with a digital interface for applications such as low-cost compassing and magnetometry. The HMC5883L utilizes Honeywell’s An-isotropic Magneto resistive (AMR) technology that provides advantages over other magnetic sensor technologies. These an-isotropic, directional sensors feature precision in-axis sensitivity and linearity.
