SparkFun Current Sensor Breakout - ACS723 (Low Current)
Description
- High accuracy board that utilizes the ACS723 for moderate AC and DC
- Measures both DC and AC currents all the way up to 5A
- The ACS723 sensor uses a Hall effect sensor to output a voltage
The SparkFun Current Sensor Breakout - ACS723 (Low Current) 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.

I have had no luck with other analog current sensors that measure 20A or higher. The output level is highly unreliable,and don't work for currents < 1.5A. Sparkfun has a good name, and this being low-current,I hope to have better luck. Will update report after testing.
Je n'ai pas eu de chance avec d'autres capteurs de courant analogiques qui mesurent 20A ou plus. Le niveau de sortie est très peu fiable et ne fonctionne pas pour des courants <1,5A. Sparkfun a un bon nom, et ceci étant à faible courant, j'espère avoir plus de chance. Mettra à jour le rapport après les tests.
Le capteur de courant ASC723 est simple d'utilisation. Lors des tests, le capteur de courant ASC723 a montré de bons résultats. Sa sensibilité de 400 mV/A offre une meilleure précision de lecture. La stabilité de son alimentation (5Vdc) indique qu'elle a une grande influence sur la précision des lectures de courant. Portez attention aux sources magnétiques à proximité du capteur de courant. Ceux-ci pourraient influencer les lectures. Après une heure d'utilisation sous une charge de 5A, la température de l'ACS723 n'est pas significative.

This return policy also applies, as a minimum standard, to products sold and fulfilled by third-party vendors through the Marketplace.
Please review the Return Conditions, Return Exceptions and the process on How to Request a Return Authorization (RA) before initiating a return request.
Returns under this policy concern non-defective products. In the case of a confirmed manufacturing defect, remedies are handled under the Warranty terms, at the Vendor's discretion. See the Warranty section.
Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
- A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- The RA number is valid for 30 days. The returned item must be received within that period.
- The RA number must be included with the return.
- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
