Raw magnetometer measurements ideally lie on a sphere centered at the origin. Due to hard-iron effects, the sphere is displaced (biased). A least-squares sphere fitting algorithm is applied first to ...

This ESPHome package allows reading your water meter or gas meter using the QMC5883L or HMC5883L or MMC5603, a triple-axis magnetometer. The magnetometer is used to read the rotating magnet inside ...

A magnetometer is an electronic device capable of measuring magnetic fields or magnetic dipole moment. Magnetometers are widely used for measuring the Earth’s magnetic field, in geophysical surveys, ...
