I2C current sensor

[mackowiakp]

Does anybody knows I2C Hall effect current sensor (10A DC) ? If so, is it supported by ESP Easy?
And second question. Is there any optoisolated extender of I2C bus ?
I want to measure DC current over cable appx 5 m long. So using ordinary connection can disturb normal ESP work and/or cause distortions of the measured current value.

For fast isolated switching, you can use iCoupler chips.
Those are in several versions available and Analog Devices even has them specifically for I2C: https://www.analog.com/en/products/inte ... ators.html#

A Hall Effect sensor is merely an analog sensor value (not sure about its linearity), so I guess you should be able to measure it with just about any A/D converter.

But in my experience measuring DC-current with a Hall effect sensor is rather tricky.
Expect a low accuracy.

OK, THX for advice !
