نحوه آدرس دهی iic :

If more than one INA219 breakout board is used, each board must be assigned a unique address. This is done with the address jumpers on the right edge of the board. The I2C base address for each board is 0x40. The binary address that you program with the address jumpers is added to the base I2C address.
To program the address offset, use a drop of solder to bridge the corresponding address jumper for each binary '1' in the address.


p to 4 boards may be connected. Addressing is as follows:
Board 0: Address = 0x40 Offset = binary 00000 (no jumpers required)
Board 1: Address = 0x41 Offset = binary 00001 (bridge A0 as in the photo above)
Board 2: Address = 0x42 Offset = binary 00010 (bridge A1)
Board 3: Address = 0x43 Offset = binary 00011 (bridge A0 & A1)

نمونه کد آردوینو :

#include <Wire.h>
#include <Adafruit_INA219.h> // You will need to download this library


Adafruit_INA219 sensor219; // Declare and instance of INA219


void setup(void) 
{
      
  Serial.begin(9600);    
  sensor219.begin();
  
}


void loop(void) 
{
  float busVoltage = 0;
  float current = 0; // Measure in milli amps
  float power = 0;


  busVoltage = sensor219.getBusVoltage_V();
  current = sensor219.getCurrent_mA();
  power = busVoltage * (current/1000); // Calculate the Power
  
  
  Serial.print("Bus Voltage:   "); 
  Serial.print(busVoltage); 
  Serial.println(" V");  
  
  Serial.print("Current:       "); 
  Serial.print(current); 
  Serial.println(" mA");
  
  Serial.print("Power:         "); 
  Serial.print(power); 
  Serial.println(" W");  
  
  Serial.println("");  


  delay(2000);
}

سلام
ببخشید خودتون اینو تست کردین
تا الان دو یا سه نمونه سنسور ولتاژ و جریان خریدم خروجی درستی ندارن
البته اونا ارزون تر بودن
