Well, I guess my question has been trending topic on this forum. I would just like to make the point and correct myself saying that IT IS possible to use a voltage divider, just need to do some calculations and choose the proper resitors, and it simply works.
Another issue is the accuracy that you can get with the sensor, taking into account that arduino's ADC is from 0 to 5V. Therefore a signal amplifier circuit is important if you want to get aa accurate measurement.
