append a \r\n to a JSON.stringify before sending to Serial1?

I would like to append a \r\n to my JSON.stringify before submitting the values to Serial1. I have:

function getSensorData() {
  var resTemp = getResTempValue(10);
  var roomTemp = 98.00;
  var ph = 58;
  var ec = 700;

  outputSensorData(resTemp.toFixed(2), roomTemp, ph, ec);
}

function outputSensorData(resTempVal, roomTempVal, phVal, ecVal) {
  var sensorData = {resTemp:resTempVal, roomTemp:roomTempVal, ph:phVal, ec:ecVal};

  Serial1.print(JSON.stringify(sensorData));
}

My Terminal window shows the json properly. However, every time the json data gets sent, the next line shows right next to the earlier json data instead of underneath. I need to append a \r\n so the string that is sent will show on the next line. How do I achieve that?

could you use Serial1.println instead of Serial1.print?

@Gordon That worked, thanks! I didn't know println existed. I need to read the documentation more closely.

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
