500A DC current sensing using hall effect sensor

[salil_desai]

how did you do it??..m goin to work on it the 1st time..i want to measure a load current(DC) of 500A using micro-controller..m gona use CS3505..and a torroidal core...thats it...thats all i know..m trying to build it on my own..i dont know anything about how much flux is induced in wat core and its relation to the voltage generated on Vout of 3505..somebody please guide me..

Try using current transformer to lower down the current. With this high current, most likely most of the device will not be able to measure them.
