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 L2C address 0x30 Monolithic integrated 3- magnetic sensor Excellent dynamic range and accuracy: 30 G 20 Bitwise operation mode 0.0625mG per LSB resolution Implementation of 2mG total RMS noise Heading accuracy of 1 The true frequency response of the sensor can reach up to 1KHz L2C peripheral, fast ( 400 KHz) mode On chip automatic demagnetization with built-in SET/RESET function Eliminating offset errors caused by thermal changes (open field output) Removing residual magnetization generated by strong external fields On chip sensitivity compensation, on chip temperature sensor (Due to different lighting or displays, there may be color differences in the actual product, which not affect the use) Color: Material: PCB Package Contents: 1 * Triaxial magnetometer with pin Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
