HJGMAG803GX Three-Axis High-Precision Weak Magnetic Field Measurement Module
HJGMAG803GX is a domestically produced, three‑axis, high‑precision weak magnetic field measurement module. The circuit comprises an oscillation source, an acceleration network, a drive network, an amplification network, a synchronous demodulation network, an integration network, a feedback network, and a bias circuit. It employs a magnetoresistive sensor architecture to measure the ambient geomagnetic field. Due to the presence of a feedback network, the circuit operates as a closed-loop system. Consequently, compared with conventional magnetoresistive sensors, the HJGMAG803GX circuit offers superior detection accuracy, enhanced reliability, excellent stability, and high sensitivity, making it suitable for applications such as navigation systems, orientation sensing, and magnetic field strength measurement. It also enables mutual conversion between geomagnetic signals and voltage signals.
