Great for learning electronics
Bought this for a university project. The documentation online is plentiful, and the module itself is robust. Easy to integrate into circuits.

Bulk purchase success
Ordered ten of these for our makerspace. All units tested perfectly out of the box. A staple component for our power supply workshops.

Good accuracy, needs filtering
The sensor is accurate, but I had to add some software filtering to smooth out the noise in the analog reading. Otherwise, it performs as expected.

Reliable current monitoring
I used the 20A version to monitor battery discharge on my robot. It has been running for weeks without any issues. Highly recommended.
Q: Does this come with screw terminals or do I need to solder wires?
A: Most versions of this module come with pre-soldered screw terminals for easy connection of high-current wires, though some bare board variants may require soldering.
Q: How do I calibrate the sensor for more accurate readings?
A: You can calibrate by measuring the output voltage at zero current and at a known load current, then adjusting your code's scaling factor accordingly.
Q: What is the maximum voltage I can apply to the VCC pin?
A: The operating voltage range is typically 4.5V to 5.5V. Please do not exceed 5.5V to avoid damaging the sensor chip.
Q: Is electrical isolation provided between the high current path and the logic pins?
A: Yes, the Hall effect technology provides galvanic isolation between the current conduction path and the signal processing circuitry, rated up to 2.1 kV RMS.
Q: Can this sensor measure AC current as well as DC?
A: Yes, the ACS712 and ACS724 modules can measure both AC and DC current. The output voltage will center around VCC/2 for zero current and vary proportionally.
