after a brief read of the datasheet, the components are included on the sensor board. you can connect +5Vdc to the 5V hole, ground to the GND hole, and the Arduino analog pin connects to the Vo pin. keep in mind that this sensor has a gain control, so check the output with a multimeter to assure it is less than, or equal to 5Vdc.~Travis
What about measuring voltages with voltage divider that are above 5V, since arduino pins can take max 5V , what do you suggest maybe some OP amp would do the trick?
