hall effect current sensor for measuring ac current

[raman00084]

i am using wcs1600 hall effect current sensor for measuring ac motor current but the out put of hall effect sensor is ac how to connect to microcontroller adc pin, if i convert to dc using diode the output is not leaner pls give any ideas

Can you post a link to an English datasheet and application notes for the wcs1600?
All I seem to be able to find are in Chinese(?)

There is a circuit which turns an op amp into a precision rectifier, by adding a diode and a resistor or two.

As an alternate method you can add DC to your signal with a potentiometer:

Use diode and add 0.7V to adc value. You can also do as BradTheRad has mentioned. You add some 2.5V to it so that the value gets shifted to the +ve side.

Start a new circuit by selecting "Blank Circuit", the last item in the Circuits menu.

You can also highlight the entire circuit, and select Cut from the Edit menu.

Save your schematic by selecting 'Export' in the File menu. Copy the text you see in the window. Paste it into a text processor, and save it to disk.

Import a schematic by selecting 'Import' in the File menu. Paste the text which you copied from a word processor.

You can use RMS to DC converter ICs from Analog Devices
