| Visual Cue | Narration |
| Slide 1: | Welcome to the Spoken Tutorial on Introduction to IOT. |
| Slide 2:
Learning Objective |
In this tutorial, we will learn about:
|
| Slide 3:
Pre-Requisites |
To follow this tutorial, you should have a basic knowledge of:
|
| Slide 4:
System Requirement |
To record this tutorial, I am using:
|
| Slide 5:
IoT - Internet of Things |
|
| IoT- Example - smart home |
|
| Image Smart Supply Chain.png | Smart supply chains help in real time tracking of goods while they are on the road. |
| Image Activity Tracker.png | Activity Trackers helps to capture heart rate pattern, calorie expenditure etc |
| Slide 6:
Working of IOT: |
IoT systems has 4 main components:
|
| Point to sensors | Sensors collect the data from the surrounding environment where the IoT system is kept. |
| Point to connectivity | The data collected by the sensors need to be sent to the end user.
We can use any wireless communications to send and receive data. |
| Point to Data Processing | Data processing involves checking the format or type of data sent by the sensor. |
| Point to user interface | The raw data which was collected by the sensor is delivered in synchronized form to the end user. |
| Slide:
About Thinkspeak |
We will use ThinkSpeak platform to demonstrate the working of IoT.
|
| Open the browser. | Let us go to Thingspeak webpage.
Open the web browser in your computer and go to this link. |
| First we have to create an account in Thingspeak before proceeding further. | |
| How to create an user account
Open this page in browser Enter email id, location, first and last name Click on continue |
Below the Email textbox, click on Create one option to create a user account for yourself.
In the Email address column, enter your working email ID. In the Location section, select the country you are living in. Enter your first and last name in respective columns. Click on the Continue button. |
| Click on the Checkbox
Click on the continue button. |
To use this application as a MATLAB platform, you must enter your work or organization email ID.
In this tutorial, we will not use the MATLAB platform. Click on the checkbox for “Use this email for my MathWorks Account”. Then click on the Continue button. |
| Point to the message
Open the email Click on verify your email button. |
You will receive a message to verify your email ID for this website.
Open the email and click on Verify your email button. It will show as “ Your profile was verified”. |
| Type the password
Click on continue. |
Go back to your login page and click on Continue.
You will be asked to create a password for your ThingSpeak account. Type your password and click on the Online Service Agreement checkbox. Click on Continue. |
| Point to the message
Click on the OK button. |
A Sign-up Successful screen appears with your registered email ID.
Click on the OK button. |
| Select personal, non commercial projects
Click on the OK button. |
It will finally ask the intent of using ThingSpeak platform.
Select Personal, non commercial projects and click on the OK button. Close the current tab and open the following link in a new tab. |
| Login to Thingspeak
Click on New channel buton |
Login to your ThingSpeak account with your registered email ID and password.
Click on the New Channel button. |
| Create New Channel with the information | I will give the channel name as DHT11_IoT.
In the Description field, I will give the description as IoT, DHT11, ESP8266-01. It makes it easy for others to find your channel on ThingSpeak server if you wish to publish it. As we want to save temperature and humidity data, type Temperature in Field 1 Click on the Field 2 checkbox and type Humidity. Now scroll down to the bottom of the page. Click on the Show Status check box. Now click on the Save Channel button. This is how the graph outline will look once the channel is created. |
| Click on the API Keys | Click on the API Keys option on the top menu.
Once the channel is created, it will generate a Write API key and Read API key. API key is called Application Programming Interface key. These are 16 digit code used for programming purposes. |
| Point to the keys | Write API key is needed when you want to store data in the channel.
Read API key is needed when you want to retrieve the data already stored in the channel. |
| From the generated API keys, we will need the Write API key while writing the code.
Copy the Write API key and paste it in any text editor like Notepad. We will require this key for future use. | |
| Slide 7:
Brief about next tutorial |
In the next tutorial, we will see how to
