inconsistent Raw BioZ Values from Identical MAX30001 Sensors #1

Software:

[protocentral_max30001](version: 1.2)

Steps to Reproduce:

Connect both MAX30001 sensors to the same Arduino board. Configure both sensors with identical settings (e.g., sample rate, gain, lead-off detection). Place electrodes in the same locations on two different subjects (or the same subject for multiple readings). Read raw BioZ values from both sensors simultaneously. Observe the difference in the values.

Expected Behavior:

I expect the raw BioZ values from both sensors to be relatively close to each other, given the identical setup and conditions.

Actual Behavior:

The raw BioZ values from the two sensors show a significant difference, even when measured under the same conditions. The values can sometimes differ by orders of magnitude. BioZ raw: 524191, BioZ raw: 70. two values of sensors.

Bioz raw's data is a bit different... Is it possible to swap two modules for testing? I think there's something wrong with the programme.
