Breakout Current Sensor ACS723 - SparkFun
The SparkFun Current Sensor Breakout is a High Precision Card that uses the ACS723 for Moderate AC and DC Current Detection Applications. The ACS723 Sensor uses a Hall Effect Sensor to Emit a Voltage relative to the Current that flows through the IP + and IP- Pins on the Board. The advantage of using a Hall Effect Sensor, specifically, is that the Circuit Being Detected and the Sensor Reading Circuit are Electrically Isolated, which means that although your Arduino is Operating at 5V, the Detected Circuit may be Operating at Higher DC or AC voltages.
The Breakout of the SparkFun Current Sensor measures DC and AC Currents up to 5A, has Complete Electrical Isolation from Measured and Detected Circuits and has a Basic Sensitivity of 400mV / THE. Although the Analog Output is Adjustable to 80kHz, the Bandwidth in the ACS723 Sensor's Break Width Filter has been set to 20kHz to Reduce Noise when Using with High Gains. The Total 80KHz Bandwidth that the Sensor is capable of can be recovered by closing the JP1 (Bandwidth Selection) Jumper on the Back of the Board.
Note: Although the Chip itself is rated for up to 2.4kV (RMS) of insulation, the board was not designed for such high voltage applications.
