So I was thinking it would be handy to have an amp clamp like device via an arduino so I can do what I want with it.
Here's what I'm thinking..
I work in the Industrial Battery Industry and we repair and maintain them. For testing we use a load bank that puts the equivalent of a forklift usage on said battery for 6 hours to determine how well the cells manage.
Each hour we take readings of all the cells and then have to readjust the load bank because the draw dissipates a little over time. So I want to put a dedicated sensor on the load bank with a nice little LCD that displays the amps so we don't need to get an amp clamp (Not like its much work, but hey)
So I was thinking a hall sensor (Never used before) but most I've seen only go up to 100A. We go just a bit higher sometimes depending on the battery in question... so don't know if this is viable.
My other thoughts were of a sort of shunt internally between the Pos/Neg output cables (Never made anything like this, but through my work I've seen them used)
Any thoughts fellas?
