Overview
The Honeywell HMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface. It is particularly suited for applications such as low-cost compassing and magnetometry. The HMC5883L integrates state-of-the-art, high-resolution HMC118X series magneto-resistive sensors along with an Application-Specific Integrated Circuit (ASIC) that includes amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit Analog-to-Digital Converter (ADC). This configuration enables the sensor to achieve 1° to 2° compass heading accuracy. The module communicates via an I2C serial bus, facilitating easy integration with various microcontrollers and other devices.
