product description

The ER-EC25B is a low-cost three-dimensional electronic compass (single board) that uses the hard magnetic and soft magnetic calibration algorithms of the US patent technology to enable the compass to eliminate the effects of magnetic fields through calibration algorithms in environments with magnetic interference. The ER-EC25B integrates 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 tilt angles of up to ±85°. Accurate heading data. The electronic compass integrates high-precision MCU control with diversified output modes. The standard interface includes RS232/RS485/TTL interfaces, and other communication interfaces can be customized.

The ER-EC25B is 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 also make the compass work in extremely harsh environments, which is more suitable for today's small Chemical military high precision measurement integrated control system.
