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.

5 FAQ

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?
