1. Use high-quality materials with guaranteed quality 2. A magnetometer can sense where the strongest magnetic force comes from and can be used to measure magnetic fields 3. This product does not require welding! Simply connect to your favorite microcontroller to quickly obtain magnetic measurements 4. The sensor can sense within a range of ± 30 Gauss (± 3000uT or ± 3mT) without the need for range setting, and can output up to 1000Hz rate readings in all 20 bits. This range is very suitable for reading the Earth's magnetic field (with a maximum value of approximately 0.6 Gauss) or some basic magnets 5. This product has been fully assembled and tested. Comes with a little 0.1inch standard connector in case you want to use it with a Breadboard or perforated plate. Four 2.5 mm (0.1 inch) mounting holes make installation easier, Weight: 0.00881849048 Pounds, Manufacturer: Ehwisbe
