The electronic compass integrates a three-axis magnetic field sensor and a three-axis acceleration sensor. It uses an industrial microcontroller with high reliability and strong anti-interference ability to calculate heading data in real time, and uses a three-axis accelerometer to compensate for heading angles over a large range.

Feature

Electrical compass sensor adopts hard and soft iron calibration algorithms, combined with high-precision accelerometer for tilt compensation to ensure high accuracy of direction measurement.
It has high resolution and strong noise resistance, and stable temperature offset, ensuring data reliability under various environmental conditions.
The electronic compass has an IP67 waterproof rating, making it perform well in harsh environments such as drilling measurements.
3D electronic compass sensor is compact in design, low in power consumption, and provides high performance and stability, suitable for various application scenarios.

Tips: Installation instructions for high-accuracy electronic compass sensor

Since high-precision electronic compass relies on geomagnetic principles for azimuth measurement, it is essential to install it in an environment with minimal magnetic interference. Ensure that the sensor is placed as far away as possible from iron objects, magnets, engines, and other magnetic materials. Even in the presence of these magnetic sources, maintain a minimum distance of at least 30cm from the compass, as the interference distance may vary depending on the strength of the magnetic field. To achieve optimal measurement performance, use anti-interference screws during installation.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
