Hi,
Can any body share connection schematic of nodemcu and ADC712 to measure current.

Looks pretty simple as from what I see you only have +V, GND and Vout which goes to the AO pin.
There are plenty of tutorials and video's on the web as well.

As stated, the connections are simple. But the results are less than spectacular. The ESP8266 has a shitty, noisy, A/D converter. The ACS series of sensors are noisy and needs filtering.
At work we have a few products designed around this manufacture's technology. I really don't like them, but they are easy to get results from.

What about Yhdc sct-13-000 trnasformer coil? Is it same noisy as ACS712?
How to conect it with nodemcu?
