Datasheet

The Grove - ±5A DC/AC Current Sensor (ACS70331) is a high precision DC/AC

current sensor based on ACS70331. The ACS70331EESATR-005B3 is Allegro’s

high sensitivity, current sensor IC for <5 A current sensing applications. It

incorporates giant magneto-resistive (GMR) technology that is 25 times more

sensitive than traditional Hall-effect sensors to sense the magnetic field generated by

the current flowing through the low resistance, integrated primary conductor.

The Grove - ±5A DC/AC Current Sensor (ACS70331) can measure both DC current

and AC current up to 5A with a base sensitivity of 200mV/A.

Danger

The human body is forbidden to touch the module during the test, otherwise there is

danger of electric shock.
