Drone-based magnetic surveying is rapidly becoming one of the most effective ways to detect buried metal objects, map subsurface anomalies, and perform geophysical exploration over large areas. With modern UAV platforms and advanced magnetometer technology, it is now possible to create a powerful DIY drone kit for professional-grade surveys. In this guide, we explain how to build a  DIY Drone Magnetometer Kit  using the  FG Sensors 3-Axis Magnetometer Kit , combined with  PolarWave AutoPilot...

Create a low-cost, traffic monitoring system by deploying the FG-3+ fluxgate magnetometer near roads to detect magnetic disturbances caused by passing vehicles. Use the Arduino UNO R4 WiFi to detect vehicles, and optionally timestamp data, and upload real-time traffic analytics to the Arduino Cloud for remote monitoring and historical trend analysis.

In today’s world, where security threats are becoming more sophisticated, it’s essential to rely on advanced and non-intrusive screening solutions. One of the most reliable and effective tools used in modern security systems is magnetometer security —a method that detects magnetic disturbances caused by concealed metallic objects. The FG-3+ Sensor  by FG Sensors , a high-precision single-axis magnetometer  is optimized for use in walkthrough detectors and perimeter security systems....
