3D Magnetic Compass Water Proof Robotics 3 Axis Digital Compass Sensor EC336


Product Description

EC336 3 Axis Digital Compass is a high-performance, low-power consumption, tilt-compensated electronic compass module that provides industry-leading heading accuracy. The EC336 combines patented magneto-inductive sensors and a 3-axis MEMS accelerometer with SkyMEMS individual factory calibration and advanced field calibration algorithms to ensure absolute accuracy.

EC336 adopts advanced field calibration algorithms which can correct the local magnetic distortions.

The EC336 working principle is utilizing magneto-resistive sensor sensing the Earth's magnetic field component to get an azimuth angle. It adopts solid state compass design, it has stable operation, high accuracy and advanced hard iron compensation function. It can overcome surrounding magnetic interference. Baud rate is optional.

Technical terms

1. Declination Angle

It is the angle between magnetic north and true north. Declination angles of different place are different, even at the same place declination angles varies with the time. When we use compass to navigation, we get directions relative to magnetic north. So we can get directions relative to true north through declination angle compensation. For example, the current direction counted by compass is north by east 30 degrees and the declination angle is 5 degrees. So the direction relative to true north is 35 degrees (30+5°=35°).

2. Installation Angle

There is an arrowhead on the compass module and it’s used to denote directions. When installed, it requests that forward direction of the object surveyed is consistent with the arrowhead. So the direction counted by the compass is the right direction. If installing direction is not consistent with the arrowhead, there is an included angle and it is the deviation angle. Only after we compensate it, the compass outputs the true direction.

3. Calibration

It’s also called hard iron compensation. All digital compasses must be calibrated before been used. Once hard iron conditions changed, the magnetic field conditions will be changed too. At this time, angle information counted by the compass will be inaccurate. In order to remove the influence, it’s necessary to calibrate the compass.
