INA3221

Current and voltage sensor INA3221 for Espruino + ESP32

Modify board for 3 independent channels [optional]

(see images folder)

Example

//setup communication bus
I2C1.setup({scl:D22,sda:D21});

//create sensor
var INA3221=require("https://github.com/devalexqt/ina3221/blob/master/ina3221.js");
var ina = new INA3221(I2C1, { 
      average:1024,
      shunt:0.1, 
      maxCurrent: 10,
    });
    
//Read data from sensor
  var data={
    ch1:ina.read(1),//channel 1
    ch2:ina.read(2), // channel 2
    ch3:ina.read(3), //channel 3
  }; 
  console.log("==>ina:",data);    

//output
==>ina3221: {
  "ch1": { "vshunt": 0, "vbus": 0, "power": 0, "current": 0 },
