Hall effect current sensors


Has anyone use a closed loop hall effect current sensor in place of the usual CT with the EmonPi? I’m looking at a couple of 200A Harting hall effect sensors for a 3-phase installation.



Two sensors - I take it that you have a 3-wire installation then? This is unusual in the UK.

People have used Hall effect with an emonTx, or more usually with a custom front end and an Arduino board. I’ve not noticed anyone trying to use those with an emonPi, because it’s most likely going to need modification to the input circuitry.
