Current sensor for arduino

[LOUIZY]

Hey, I m part of solar car project, we are making a car that runs using only solar energy, the energy is stocked in a battery, and I need to monitor the current that enters the battery (output of the solar panels/MPPT), I m looking for a current sensor that can mesure current from 10A to 15A using hall effect, I was using the LEM LA 25-p current sensor, but its output is not suitable with the arduino and unlike what i need this sensor requires a symmitrical input voltage (+12v -12v), I m opened to any suggestion,
here is the link for the LEM current sensor I have:

Try one of these. Costs a little, does a lot, lasts a long time... easy to interface to PICs or Arduino. There is a (longish) thread here at EP on how to use an Allegro current sensor with a PIC microcontroller for AC sensing, but DC sensing is even easier. Suggest you investigate using the Allegro ACS723.

Similarly the ACS712 is $1.50 on ebay with board and terminals.
