Did you ever get anywhere with using the LEM 55-p to an arduino? i am trying a simular project with the LEM-55p hall effect sensor with mA output for non-contact current measurement. my idea is to use a 24vDC source to the power the sensor i only plan on using the sensor in one direction, i know the data sheet source says +-12V but i read here ( http://www.lem.com/hq/en/content/view/208/157// ) that you can use a unipolar source but it has to be double the bipolar source, also it will only measure in one direction. My goal is to use the LEM 55-p with an arduino microcontroller for signal processing into an LCD to read the measurement current proportional to the current carrying conductor going through the aperture. i am confused how you would go about conditioning the circuit to the range of the ADC of the microcontroller, any insight would be appreciated!

ps sorry for commenting on an old post, but i am unsure where to go and have searched the web top to bottom.
