HMC5883L Module, 3-Axis Digital Compass

The Honeywell HMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface for applications such as lowcost compassing and magnetometry. The HMC5883L includes our state-of-theart, high-resolution HMC1 1 8X series magneto-resistive sensors plus an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables 1 ° to 2° compass heading accuracy.

The HMC5883L utilizes Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over other
magnetic sensor technologies. These anisotropic, directional sensors feature precision in-axis sensitivity and linearity.
These sensors’ solid-state construction with very low cross-axis sensitivity is designed to measure both the direction and
the magnitude of Earth’s magnetic fields, from milli-gauss to 8 gauss. Honeywell’s Magnetic Sensors are among the most
sensitive and reliable low-field sensors in the industry.
