could i use this sensor oh49e to measure current ranging from 0-5 A to monitor it on lcd using microcontroller?

 

Data sheet

You might need to wind the current-carrying conductor into a solenoid on a core, and then insert the hall sensor into a gap in the core to get enough sensitivity...

 

As Mike indicated, building your own Hall effect current sensor would take a little bit of work. Why not consider this: https://www.sparkfun.com/products/8882?gclid=CImwlqyD68kCFUWVfgodF1wBBA

That would appear identical to what he has, he would still need a magnet/transducer of some kind?
Max.

 

Hello,

Or you could have a look at the sensor attached in the PDF.

...the simple answer is yes you can. To get started read about the principles, there are loads of examples online:

Nope
An OH49e is a raw Hall effect device. It has no input current terminals.

The sensor I linked to is complete.
