hello old gentlemen,
please suggest to me an AC current sensor device that can be used for the ESP8266,
where the point I want is
The device lasts 24 hours non-stop
valid sensor data,
I tried researching on Google to get the ZMCT103C brand, what do you think about the ZMCT103C device, are there any suggestions for other devices?

Hi @horasjey
What is the current range you want to measure?
hi @jim-p , thanks for your respound,
i think range under 10A

horasjey:
i think range under 10A
Any documentation I see for the module says 5A
I've moved your topic to a more suitable location on the forum.
This is the description for Suggestions for the Arduino Project - Arduino Forum
So not for suggestions for your project

You may consider this one. It will output 0 to 1V for a 0 to 10A input
Order today, ships today. 101990059 – 10 A Current Sense Transformer Chassis Mount from Seeed Technology Co., Ltd. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

I would simply use google, these are sold by the thousands for HA projects.

used the SCT-013 current clamp on a number of projects - range upto 100amps
I see the shape of the device at the end of the cable using a 3.5mm audio jack or 3-pin header, how do I connect it to the ESP8266...? since there is no 3.5mm audio jack or 3-pin header port on my esp8266,
Is the 3.5mm audio jack or 3-pin header cut?

Do you know how to solder?

remember the output of a SCT-013 current clamp is an AC voltage
the ESP8266 ADC reads DC so you need to offset the AC voltage - see measure-ac-current-using-arduino-and-sct-013 for a circuit alternatively see ESP8266 Mains Current Sensor module
you will need to sample for several AC cycles to calculate the RMS current

You can use one of these or something similar.
TRRS connectors are the audio-style connectors that you see on some phones, MP3 players and development boards. TRRS stands for "Tip, Ring, Ring, Sleeve,"
Solder wires to the Tip and Sleeve
However, you will need to shift the signal up so that it is not negative.
If you cut it directly and solder it to the ESP8266 board without using this board, is that possible, sir?
hallo @horace ,
well noted

No, you need a small circuit to shift the voltage up so that it is not negative.
Which ESP8266 board are you using?
system
