HMC5883L Triple Axis Compass Module Magnetic Field Sensor
The HMC5883L Triple Axis Compass is a low power 3-axis Magnetometer / Digital Compass Module based on HMC5883L. The Board breaks out the I2C communication interface and comes with an onboard voltage regulator and can be powered from a 5V supply. It also has pull up resistors on the I2C line. The Compass Module is designed for low-field magnetic sensing with a digital interface and perfect to give precise heading information. This compact sensor fits into small projects such as UAVs and robot navigation systems.
The
sensor converts any magnetic field to a differential voltage output on 3 axes. This voltage shift is the raw digital output value, which can then be used to calculate headings or sense magnetic fields coming from different directions.
The module includes a state-of-the-art, high-resolution QMC5883X series magneto-resistive sensor, 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 I2C serial bus allows for easy interface
