Is there any current sensor to measure low ac current like 2-10 mA at 220VAC ? I need to measure current with microcontroller ? Could anybody give me any idea , advise , schematic ?
Thanks

Hello Mehmet,
There is a TI design for 2KV isolated current sensing (I have attached the file). I think this can be scaled to your application. Let me know if you have questions.

Hi, I have a similar application. Current consumption is about 100mA. Want to precisely measure this using op-amp and micro controller.
Can 230VAC be given to isolation op-amp?
