DC 5V Magnetic NS Pole Detection Pen Portable Hall Module NS Discrimination High Sensitivity ±5mT with Green/Red LED Indicator

Product Features1. Using Hall modules to accurately distinguish magnetic poles, easily identifying north and south poles.2. High sensitivity, sensitivity of 5mT, detectable by weak magnetic fields.3. The body is compact and portable, carrying it around without any burden.4. Supports 5V power supply, can be powered by a mobile phone charging cable.5. The green light displays N poles and the red light displays S poles, making it clear and easy to understand.Product Parameters:Product Name: Magnetic Pole Detection ModuleInterface: Type CPower supply method: 5V power supply (do not use fast charging adapter)Detection sensitivity: ± 5mTDimensions: Length 55mm x Width 10mmIndication method: Green light indicates N pole, red light indicates S poleCore function: Accurately distinguish N and S pole magnetic fieldsOperation requirement: The detection surface should be perpendicular to the detected magnetic fieldUsage:Plug in the data cable, the detection surface is perpendicular to the detected magnetic field, and the green light indicates the N pole; The red light indicates the S pole.Product List:1X detection module
