Description
Product Description:
This is a breakout board for the fully integrated linear ACS712 current sensor. The sensor gives precise current measurement for both AC and DC signals. Thick copper conductor and signal traces allows for survival of the device up to 5 times over current conditions. The ACS712 outputs an analog voltage output signal that varies linearly with sensed current.
ACS712 is based on Hall detection principle, please try to avoid the magnetic field, when using as it may impact the reading accuracy.
Features:
Current sensor chip: ACS712ELC-30A.
