Default Circuit for Hall effect sensor

Hello
I recently bought a linear Hall effect sensor for measuring current, but I don't know how to make the circuit to measure the current, could anybody help me with this? Please tell me the circuit.
Thank you very much!

Hello,

A lot of information on Hall sensors can be found in the links from this page:

@bertus
Thank you. And after I measured the output voltage of the hall effect sensor, how can I know the current in primary wire?

The device should have a data sheet that states the sensitivity of the sensor. Even so, you will probably need an ammeter to help calibrate the Hall effect sensor output.

You need to either use a micro to do the scaling or have some manual scaling factor (for example 10mV=1A)

I've got a project that uses a hall sensor.. calibration is a pain. Mine measures up to 600 Amps DC. Sensor spaced approx. 3/16" off a copper bus bar.

How can I know the scaling factor?

Default Block diagram for Hall effect sensor

Does anybody know the block diagram of Honeywell CSLA2EL Hall effect sensor ?
And how to use this sensor to make a circuit for measuring current?
And how can i know the relation between the output voltage and primary current?
Thank you!

Greetings chudiandeyu,

I have merged both of your posts since they appeared to be identical.

Hello,

All information on sensitivity and size are in the attached datasheet.
