Okay for low precision tasks
It works, but don't expect lab-grade accuracy. There is some drift depending on temperature. Good for learning though.

Good value but needs filtering
The sensor is accurate enough for hobby use. I had to add a capacitor to smooth out the noise in the analog reading.

Fast shipping and well packaged
Arrived quickly and was protected well in anti-static bag. Pin headers were included which was a nice touch.

Great for motor current sensing
I am using this to monitor a DC motor current. The isolation gives me peace of mind when connecting to microcontrollers.

Perfect for Arduino Projects
Works exactly as described. I used the 20A version for a battery monitor and the readings are stable after calibration.
Q: Can this sensor measure AC current?
A: Yes, the ACS712 can measure both AC and DC current. You will need to process the analog signal appropriately in your code for AC.
Q: What is the response time of the sensor?
A: The typical output rise time is 5 microseconds, making it suitable for most real-time monitoring applications.
Q: What is the output voltage at zero current?
A: The output voltage at zero current is typically VCC / 2, which is around 2.5V when powered by 5V.
Q: Does the package include screw terminals for high current wiring?
A: No, this module uses heavy gauge copper pads for current flow. You should solder your wires directly to the pads for best contact.
Q: Is this module compatible with 3.3V logic microcontrollers?
A: Yes, the output is analog. However, ensure your MCU ADC reference voltage is compatible or use a voltage divider for the output signal.
