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.

Based on Allegro’s high sensitivity current sensor IC; ACS70331EESATR-005B3, it’s suitable for <5A current sensing applications, alongside its base sensitivity of 200mV/A!

The Grove - ±5A DC/AC Current Sensor (ACS70331) can measure both the DC current and the AC current up to 5A with a base sensitivity of 200mV/A.

What is the current sensor? 

A current sensor is a device that detects electric current in a wire and converts current to a voltage that can be easily measured. Also, this will be proportional to the current through the measured path.

Current sensors are usually designed after taking two phenomena into consideration.

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 mΩ 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)

What is Grove?

Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs. Not only are these open hardware, but we also have open-source software.
