HMC5883L Triple Axis Compass Magnetometer Sensor Module

The module is based on the Honeywell HMC5883LIC for low-field
magnetic sensing with a digital interface for applications such as
lowcost compassing and magnetometry. The HMC5883L includes
state-of-threat, high-resolution HMC118X 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 I2C serial bus allows for an easy
interface.

TheHMC5883Lutilizes
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 Earths
magnetic fields, from milli-gauss to 8 gausses. Honeywells Magnetic
Sensors are among the most sensitive and reliable low-field sensors in
the industry.

Note:

Sometimes
markings on these boards vary slightly (e.g. Some may be labeled HW-127
instead of GY-273 even though they are otherwise identical).

Applications:

1. Auto and personal navigation.
2. UAV systems.
3. Robotic navigation.
4. Location-based services (LBS).

Features:

1. 1-2 degree heading accuracy.
2. A range of -8 to +8 Gauss.
3. Communication: IIC communication protocol.
