MPRL Pressure Sensor (Adafruit Breakout Board) - Reading sensor data via I2C

And finally the code with the psi-output value:

var i2c = new I2C();
i2c.setup({ scl : D29, sda: D28 });
var output_bit;
var output_max;
var output_min;
var P_max = 1;
var P_min = -1;
var pressure1;
var pressure2;
var pressure_final;
setInterval(() => {
i2c.writeTo(0x18, 0xAA, 0x00, 0x00);
  setTimeout(() => {
  let output = i2c.readFrom(0x18, 5);
    var output_bit = output[1] *100 *100 + output[2]*100 + output[3];
    console.log(output_bit);
    var pressure1 = (output_bit-1200000)*(1-(-1));
    var pressure2 = pressure1/(1500000-1200000);
    var pressure_final = pressure2 + (-1) - 0.4;   
    console.log(pressure_final);
  }, 100);
}, 300);
