Product Details

High Precision 3D Electronic Compass


Introduction

The ER-EC29B is a low-cost 3D electronic compass that uses US patented hard magnetic and soft magnetic calibration algorithms to enable the compass to eliminate the effects of magnetic fields through calibration algorithms in environments with magnetic interference. The ER-EC29Bintegrates a three-axis fluxgate sensor that solves the heading in real time through a central processor and uses a three-axis accelerometer to compensate for heading over a wide range of tilt angles, ensuring that the compass provides high precision at tilt angles up to ±45°. Heading data. The electronic compass integrates high-precision MCU control and has a diversified output mode. The standard interface RS485 interface can also be customized for other communication interfaces.

The ER-EC29Bis small in size and low in power consumption. It can be used in many fields such as antenna stabilization, vehicle and system integration. High shock resistance and high reliability make the compass work in extremely harsh environments, which is more suitable for today's miniaturized military industry. High precision measurement integrated control system.
