Now, we will set up the app and write the required code:

1. From the Terminal, once you are inside the IBM-IoT-Device folder, run the following:

$ npm init -y

$ npm install ibmiotf --save

3. Next, we will install rpi-dht-sensor (https://www.npmjs.com/package/rpi-dht-sensor) from npm. This module will help in reading the DHT11 temperature and humidity values:

$ npm install rpi-dht-sensor --save

4. Your final package.json file should look like this:

{  "name": "IBM-IoT-Device",  "version": "1.0.0",  "description": "",  "main": "index.js",  "scripts": {    "test": "echo "Error: no test specified" && exit 1" }, ...
