Program to print temperature

Write the following code in Cloud9 and save it as tmp36.js. Run the program and check the printed temperature. Then touch the plastic body of the sensor for a few seconds (avoid touching metal pins). You should see an increase in temperature. The code for tmp36.js is as follows:

var b = require('bonescript');
var loopTimer = setInterval(readVoltageLoop, loopTime);
var loopTime = 2000;
var TMP36 = 'P9_40';

function readVoltageLoop()
{
  b.analogRead(TMP36, printTemperature);
}

function printTemperature(pinObj)
{
  var volt = pinObj.value * 1.8;
  var temperature = (100 * volt) - 50;
  console.log("Voltage at input pin = " + volt.toPrecision(3) + " Temperature in Celsius =" + temperature.toPrecision(3) );
}

Explanation

We want to print the temperature after every 2 seconds. So, we created a timer using setInterval(). This timer will call the function readVoltageLoop() after every 2 seconds. The function readVoltageLoop() calls analogRead() on pin P9_40. The first...
