Metal Detector & Magnetometer transforms your device into a precision magnetic field detector. Measure magnetic fields in real-time with detailed 3-axis data visualization. FEATURES: • Real-time magnetic field strength measurement in microteslas (µT) • 3-axis breakdown (X, Y, Z) of calibrated magnetic field readings • Color-coded alerts: green (normal), yellow (elevated), red (metal detected) • Manual calibration to set a baseline reference value • Uncalibrated sensor data with iron bias correction • Geomagnetic rotation vector display • Magnitude history tracking • Adjustable sensor sampling rate PERFECT FOR: • Finding metal studs, pipes, and wires in walls • Detecting hidden ferromagnetic objects • Science experiments and educational use • Exploring magnetic fields in your environment IMPORTANT: This detector works with ferromagnetic materials only (iron, steel, nickel). It will not detect non-ferromagnetic materials like aluminum, gold, or copper.
