Hello.
Currently doing a school project measuring how much concentrated salt there is in a volume water, and then building a modell that can read how much it is. We decided that we were going to build a resistance wheatstone bridge followed by differntial amplifier into a full wave rectifier so we can turn Ac into Dc. The reasoning behind Ac is to not get a higher resistance when the salt starts to form crystals on the metal parts that is measuring the resistance. But now I have run into a problem with designing the full wave rectifier. The voltage will go from around 0 to 1.5. And I do not know how to design the Full wave rectifier accounting for range. Thanks in advance and sorry for my poor English skills.
