I want to measure the oil content and moisture to the skin.
I use this chip, the AD5933 chip found.
But I do not know how to spend the chip yet.
I do not know've also data sheet.
Can you ever tell if circuits or data associated with this chip?

You need a data sheet?

I have AD5933 datasheet
What I wonder is a circuit choreography of ad5933.
i saw ad5933 datasheet. but i don't undertstand that

Impedance at different frequencies? That seems to be what the AD5933 is designed for.

I was thinking the same but apparently some studies were done back in the 1950s and it seems there is a lot of variability from person to person but not much variability in one person over time. Therefore, it would be difficult to calibrate a meter for any small variability in skin conditions without having a baseline for each individual.

That would seem to make it complicated

Hello,
the chip is ADC itself.
What are you trying to solve?

The chip is NOT an ADC, it has an ADC built into it with lot of additional circuitry. Rritesh, why don´t you stick to threads that are at your level of expertise and stop posting irrelevant or incorrect replies? Lately you seem to have something to say to almost everything and everytime you are either talking about something completely different or not helping at all.
