GY-273 HMC5883L 3 Axis Module Magnetic Field Sensor

GY-273 HMC5883L 3 Axis Module Magnetic Field Sensor

The GY-273 module is built around the Honeywell QMC5883L IC, designed for low-field magnetic sensing with a digital interface, making it ideal for applications like low-cost compassing and magnetometry. The QMC5883L features high-resolution QMC118X-series magneto-resistive sensors, paired with an ASIC that handles amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC, delivering compass heading accuracy within 1° to 2°. Its I2C serial bus provides a straightforward interface for easy integration.

The QMC5883L uses Honeywell’s Anisotropic Magnetoresistive (AMR) technology, offering superior performance over other magnetic sensor technologies. These anisotropic, directional sensors provide high precision in-axis sensitivity and excellent linearity.

Designed with solid-state construction and very low cross-axis sensitivity, the QMC5883L accurately measures both the direction and magnitude of Earth’s magnetic field, from milli-gauss to 8 gausses. Honeywell’s magnetic sensors are among the most sensitive and reliable low-field sensors available, making this module a robust choice for a variety of magnetic field detection applications.

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.
