Recommend AC current sensor

I want to measure the AC shore power current usage on my boat. It is a 120v 30amp cable. I have some experience using a Adafruit esp32 feather and their mqtt data logging service “IO”

I am looking for a recommendation on which board to purchase and hopefully be able to use it with the esp32 board, and if you have a link to any arduino code to read the sensor ? Ideally looking for a sample code that can do a serial.print on the current value and I should able to take it from there.

Thank you

I would recommend this board:

Our ESP32 module here will plug into the board’s IoT socket:

We have sample code available here:

Let us know if you have any other questions.

Thank you,
