LIS3MDL noise and maximum accuracy

2023-10-04
In my system that found the heading angle using the LIS3MDL sensor, the maximum error value was 3 degrees using the ellipsoid calibration method. Also, although I used the sensor in low noise mode, I saw that the data in Matlab graphics was very wavy...

Hi,We were looking at the LIS3MDL sensor. Apparently it is a magnetoresistive sensor. When we examined other magnetoresistive sensors in the market we have seen that they need set/reset circuits in order to compensate for the disturbances in the magn...
