DESCRIPTION : GY-511 module includes a 3-axis accelerometer and a 3-axis magnetometer. This sensor can measure the linear acceleration at full scales of ± 2 g / ± 4 g / ± 8 g / ± 16 g and magnetic fields at full scales of ± 1.3 / ± 1.9 / ± 2.5 / ± 4.0 / ± 4.7 / ± 5.6 / ± 8.1 Gauss. When you place this module in a magnetic field, according to the Lorentz law, a current is induced in its microscopic coil. The compass module converts this current to the differential voltage for each coordinate direction by calculating these voltages, you can calculate the magnetic field in each direction and obtain the geographic position. It communicates using I2C communication protocol and the voltage level required to power this device is 3V-5V. You can use it in DIY GPS system, accelerometer data acquisition system to be used in Vehicles etc. GY-511 module Specifications Voltage: 3-5V I2C serial interface Chip built-in 12bit AD converter, 16-bit data output 3 magnetic field axis and 3 acceleration axis Range of ±1.3 to ±8.1 gauss magnetic field ±2 g / ±4 g / ±8 g / ±16 g user selectable full-scale acceleration ranges
