The HMC5983-TR is a linear, compass sensor IC developed by Honeywell, Inc. It is a 3-axis, magnetoresistive (MR) magnetic field sensor which can be used to detect the direction and strength of magnetic fields. The chip is highly sensitive to changes in the horizontal and vertical components of the magnetic field. The output is digitally encoded to ensure accuracy and stability.

HMC5983-TR Applications

The HMC5983-TR can be used for various applications due to its sensitivity to the magnetic field. It is used in the navigation of vehicles and robots, positioning and orientation control, navigation of submarines and underwater vehicles, dynamic magnetic field measurement, and environmental magnetic monitoring. It can also be used for heading and attitude measurement for unmanned aerial vehicles (UAVs), drones, football Launching Procedure, automated guided vehicles (AGVs), and consumer electronic devices such as smartphones and tablets.

HMC5983-TR Working Principle

The HMC5983-TR is three channels, each with a linear, magnetoresistive, MR element. The MR element responds to the magnetic field strength in a linear fashion. The linear element senses the local magnetic field vector, which is usually a wide range of low-frequency ambient and higher frequency motion-based magnetic field sources. The HMC5983-TR also incorporates signal conditioning, which amplifies and routes signals to the analog-to-digital converter.

The HMC5983-TR is then read by a microcontroller, which calculates the direction of the magnetic field vector by using a three-dimensional cartesian coordinate system. The output is digitally encoded, ensuring accuracy and stability. It also includes a temperature compensation circuit to increase temperature stability over wide ranges.

Conclusion

The HMC5983-TR Linear, Compass Sensor IC is suitable for a wide range of applications, including navigation of vehicles and robots, positioning and orientation control, navigation of submarines and underwater vehicles, dynamic magnetic field measurement, environmental magnetic monitoring, and heading and attitude measurement for UAVs, drones, football Launching Procedure, AGVs, and consumer electronic devices. The chip is highly sensitive to changes in the horizontal and vertical components of the magnetic field, and the output is digitally encoded, ensuring accuracy and stability.
