ACS712 Current Sensor - 20A

ACS712-20A Current Sensor is used to measure the intensity of the current. It contains an ACS712ELC-20A chip, based on Hall Effect. You should protect it from the influence of the magnetic field when using it.

The ACS712 is a fully integrated, hall effect-based linear current sensor with 2.1kVRMS voltage isolation and an integrated low-resistance current conductor. Technical terms aside, it’s simply put forth as a current sensor that uses its conductor to calculate and measure the amount of current applied.
