The Grove - 2.5A DC Current Sensor(ACS70331) is a high precision DC current sensor based on ACS70331. The ACS70331EESATR-2P5U3 is Allegro?s high sensitivity,current sensor IC for <2.5 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 - 2.5A DC Current Sensor(ACS70331) can measure the DC current up to 2.5A and has a base sensitivity of 800mV/A. This sensor do not support AC current, if you want to measure the AC load please check the:
Grove - ±5A DC/AC Current Sensor (ACS70331)
Note
We've Released the Grove Selection Guide and hope to help you find the Grove suit you best.
Danger
The human body is forbidden to touch the module during the test, otherwise there is danger of electric shock.
Features
1 MHz bandwidth with response time <550 ns
Low noise: 8 mA(rms) at 1 MHz
1.1 m? primary conductor resistance results in low power loss
High DC PSRR enables use with low accuracy power supplies or batteries (3 to 4.5 V operation)
