    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...

    Hello,

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

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

    The sensor I linked to is complete.
