How can I measure the original current by measuring the output of the "hall effect current sensor"?

PROMOD DEY

In the above picture original current through the circuit can easily be measure my measuring the voltage across the R3 resistor; because current=voltage/0.033.

In the above picture how can I measure the original current through by measuring the output voltage of the hall sensor effect?

Thanks in Advance!

Hello PROMO DEY,

Thanks for posting to the forum to solve your engineering needs. We are looking into this, but could you please specifiy what Hall-effect devices you are looking at? You can always view our free training videos online that go into detail about these devices.

Also, which circuit are you referring too? Please send a complete schematic with the device you are using.

Best,
