SparkFun Current Sensor Breakout - ACS723

DESCRIPTION DOCUMENTS
The SparkFun Current Sensor Breakout is a high accuracy board that utilizes
the ACS723 for moderate AC and DC current sensing applications. The
ACS723 sensor uses a Hall effect sensor to output a voltage relative to the
current flowing through the IP+ and IP- pins on the board. The advantage of
using a Hall effect sensor, specifically, is that the circuit being sensed and the
circuit reading the sensor are electrically isolated meaning that, although your
Arduino is running on 5V, the sensed circuit can be operating at higher DC or
AC voltages!
The SparkFun Current Sensor Breakout measures both DC and AC currents all
the way up to 5A, has full electrical isolation of measured and sensed circuits,
and has a base sensitivity of 400mV/A. Although the analog output is adjustable
to 80kHz, the bandwidth on the ACS723 Sensor Breakout width filter has been
set to 20kHz to reduce noise when using at high gains. The full 80KHz
bandwidth that the sensor is capable of can be recovered by closing the JP1
(Bandwidth Select) jumper on the back of the board.
Note: Although the chip itself is rated for up to 2.4kV (RMS) of isolation, the
board has not been designed for such high voltage applications.

Excellent!
about a year ago by Member #803446 verified purchaser
Board is excellent for measuring current & is priced well - the chip alone costs CAD on digikey. Another version
of this board has a 3star review due to low resolution - just want to say that this is unfair, this is an analog
device so you are limited by the resolution of your ADC - on the arduino this is 1024 steps over 5V. if your
readings are too jumpy, average them out or use a low pass filter. great product!
