TMAG5273: A2

Part Number: TMAG5273

I am using TI TMAG5273A2 hall effect sensor with ESP32. Why is there an initial offset of 3mT in y and z axis data initially when it is used with ESP32. I am simply reading the basic data from the sensor(i.e. magnetic field of all 3 axis) with default modes of the sensor through Sparkfun_TMAG5273 library in Arduino IDE. I have enabled read all 3 axis data register and put it in continous measure mode. That's the only change I have made.

    Hi Dhanush,

    Thank you for posting to the Sensors forum!

    Could you share how you are converting from the raw data value to mT? Is it the case that for the Y- and Z-axis, the output is a, relatively, constant 3mT? It should be the case that with no magnetic field present, the output switches from positive to negative.

    Is it possible that there is some kind of magnetic field near the device that it may be reading?

    Best,
