Are current sensors rated for inrush or continuous current?

Hello @danbmoreau,

There are additional consideration involving hysteresis to consider. Please see this article:

Measure high DC current with an Arduino and the LEM HO 120-P Transducer

What techniques are available to measure high current with an Arduino microcontroller? There are several different ways to measure current using a microcontroller such as the Arduino Nano Every. These methods generally fall into two categories: shared ground connection: With these methods the microcontroller must be at the same ground potential as the system being measured. The classic example is to pass the current through a low resistance shunt resistor. With the microcontroller’s ground an…

If you anticipate high peak current, you may want to investigate sensor degaussing. A resistive step-start may also be warranted to reduce the starting current.

Please let us know if you have additional questions.

Alos, kindly include a picture of your device as it sounds like an interesting project.

Best wishes,
