ESP32 Hall Sensor - Not very sensitive?

Postby Fuzzyzilla » Fri Jul 07, 2017 10:02 pm

Hello!

I have a bit of an issue. When running the Hall Sensor test, the values returned are very small (about 12), fluctuate a lot (±6), and do not change much in the presence of a large magnet (20 when 1cm away, 60 when in contact).

Others are reporting values around 5,200 which vary a lot when around a small magnet (±200). I was hoping to use the hall sensor to detect shaking, but this use is not looking possible, as shaking is not noticable against all of the noise.

What am I doing wrong here?

I think LNA not used for measurements yet.
