Great for university projects
Used this for my final year project measuring DC motor current. It handled the load without issues and data was consistent.

Good value but needs calibration
The module arrived quickly. It works well but I had to adjust the zero point in my code to get accurate readings at idle.
Q: Can this module measure both AC and DC current?
A: Yes, the ACS712 chip is capable of measuring both AC and DC current depending on your code implementation.
Q: What is the output voltage when no current is flowing?
A: At zero current, the output voltage is typically VCC/2, which is approximately 2.5V when powered by 5V.
Q: Is there electrical isolation between the current path and the sensor?
A: Yes, the ACS712 uses Hall Effect technology which provides galvanic isolation between the current path and the signal pins.
Q: Is this compatible with 3.3V logic boards like Raspberry Pi?
A: Yes, it can work with 3.3V systems, but please note that sensitivity may vary based on the supply voltage provided.
Q: Does the package include pin headers for soldering?
A: Yes, the module comes with standard pin headers included in the package.
