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

- Thu May 09, 2019 12:30 pm #82225 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.

- Thu May 09, 2019 1:35 pm #82229 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.

How to conect it with nodemcu?
