Hall effect sensor to measure current

by Nasif on Mon Feb 11, 2019 12:19 am

Hello!

Is there any way to use this hall-effect sensor to measure current? I figured because electric current generates a magnetic field around a wire, perhaps this sensor can detect that? For the moment I just need to detect if there is current passing through or not (wirelessly, which is why I'm not looking into current sensors), the amount of current is irrelevant to my project. Would this be possible with the hall effect sensor?

That particular sensor is optimized for detecting the proximity to the south pole of a magnet. The field created by current flow in a wire is probably not strong enough to trigger it - unless you are talking about very high current levels. You will have better luck using a hall sensor designed for current sensing:

Thanks a lot! I'll look into it!

[EDIT] For anyone who might end up here looking for a 'wireless' way to detect the presence of AC or DC as I was, a simpler way to do it is with an EMF detector, something like this!
