The FG-3C Magnetic Field Sensor is a fully calibrated 1-axis fluxgate magnetometer designed for precise and stable magnetic field measurements in industrial, research, and embedded applications.
It delivers linearized, temperature-compensated magnetic field data directly in nanotesla (nT), eliminating the need for external calibration or complex correction algorithms.
Each sensor is individually factory-characterized to ensure consistent accuracy and repeatable measurements. With multiple output interfaces including UART, analog voltage, and frequency/PWM, the FG-3C easily integrates into modern microcontroller systems as well as legacy measurement setups.
Whether used in geomagnetic monitoring, industrial sensing, or scientific experiments, the FG-3C provides reliable and easy-to-use magnetic field measurement in a compact and efficient design.
