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: http://www.educypedia.be/electronics/sensorshall.htm Bertus

@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.

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!

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