Is there anyone know MAX4080S arduino code to get voltage,current, and power value

[kirikazu11]

here the pic of MAX4080S (CJMCU408) . I confuse bout the coding and the wiring diagram because there isn't tutorial in Youtube. so please help me solve the prolem. your help and advice is angel guardian for me . please reply master

sorry but your link is about acs758(CJMCU 758). my sensor is MAX4080S(CJMCU 408)

Have you looked anywhere besides YouTube for documentation?

Use the search phrase "MAX4080 arduino" to find tutorials.

I confuse bout the coding

This is an analogue chip, so there is no coding.

@kirikazu11

and the wiring diagram

Well, there is VCC and GND for power.
RS+ and RS- are the shunt connections, which are duplicated on the pin header.
REF1A and REF1B are only used for MAX4081 chips.
And there is the output, which connects to an Arduino analogue input.
Gain of the 4080S is 60V/V, so 5A in a 0.1ohm shunt results in 3volt output.
Got it all from reading the datasheet. What else is there to know.

can you make the code of this sensor with its principle with read max voltage 76v ? sorry but i don't know how to make this code

[Wawa]

Did you read the datasheet?

The MAX4080S is a current sensor, not a voltage sensor.
Exactly like the INA169 in your previous thread.
The only difference is the fixed 60V/V of the MAX and the user select-able gain of the INA.
Tell us which part you didn't understand in reply#8 of that thread.
