YHDC AC Current Sensor - 30A

Hardware
1

Hi,
I am starting my testing on the current monitor (will be incorporating a voltage sensor in the final build though). I will be using mostly the YHDC AC Current Sensor - 30A sensors (individual circuits, but the 100 amp variant for total usage) and noted the spec’s state 30A/1V as appose to 100A/50mA. So following this: guide I do not need the burden resistor, but still will use 2x10k resistors and the cap?

Thanks

Correct.

The parts you mention (and this is explained fully in the guide) “bias” the signal going to the analogue input so that both positive and negative swings can be measured.

Thanks, was 99% sure - just didn’t want to blow up my house :grin:
