This is a getting started tutorial about Amazon Web Services, i.e AWS IoT Core with ESP32. The AWS IoT Core is a managed cloud service that lets connected devices easily and securely interact with cloud applications and other devices.
In this tutorial, we will learn how you can connect the ESP32 with AWS IoT Core & publish sensor reading to AWS MQTT. For a demo, we will use the DHT11 Sensor and read the humidity temperature data. The ESP32 will connect to the local WiFi network and will post the DHT11 Sensor data to AWS IoT Cloud. Not only posting data, but we can also receive the data from AWS Dashboard.
The tutorial comprises multiple sections
00:00 Overview of Amazon Web Services
02:01 Hardware & Circuit
02:28 Signing up & setting the Amazon Web Services
02:55 Arduino Sketch & Library Installation
03:26 AWS Management Console
03:50 Creating a Thing is AWS
04:30 Configure Device Certificate
04:59 Creating a Policy
06:39 Attaching Policy to Certificate
06:50 Download Certificate & Keys
07:43 Modifying Arduino Sketch with AWS Credentials
09:32 Testing Code on Serial Monitor
09:54 MQTT Test Client Subscribe
10:39 Publishing Data from AWS Dashboard
This tutorial is for beginners who want to learn about the Amazon AWS IoT Core for IoT Applications. Earlier we learned about IoT platforms like Google Firebase and Arduino IoT Cloud. But with AWS IoT Core, you can build and manage devices for commercial applications.

For those who are working currently with the latest aws version, there is an update on the Resource ARN part. Replace resource ARN path with * sign. Replacing the path with * will simply allow everything.
thank you! great help!
yes . i tried that but what data i give in subscribe data topic
Super projects with AWS, Graet explenation, THANKS
What an amazing project!
Simple and quick explanation, big thanks
This is what exactly I was looking for. Thank you for sharing!.
Oh yes, and I did Subscribe as well
Nice work!! Thank you for detail video.
Great tutorial, Beautiful Voice.
explained well, clear and Nice voice,
Vote up, nice clip, thanks for sharing :)
Best explanation ......!
Really helpful! Thank you!
This is great content ! Thanks 👌🏻
Thank you for this Lesson
This is a super good tutorial and application
Good explanation. Very Helpful
Very Useful and great explanation .Thank you so much mam.
We need more videos please....!
thankyou very much, very informative
Awesome video
Thank you for the video! but, can I do the same with a DS18B20? and how? which are the libraries I'll need? Thanks
Good explanation
soft husky voice. Thats what got me hooked!!
Hi.. i am not able to create policy. Its giving error "Policy document is Malformed: The following resources are invalid" what could be wrong ? its not showing Resource arn.
DO I NEED TO DO A SEPERATE SETUP OR CODING RO CONNECT ESP32 TO WIFI ? Cuz I don't see a place to add wifi name and pw in the provided code.
Nice video, as you said this course is for beginners, is there also a version planned with more advanced stuff?
Like how to create some kind of middleware between your devices and aws, to make sure no data are lost in case of missing internet uplink.
What do you think about the approach two use mqtt in your local network and a subscriber which will publish all events to aws, with this in place you could also use other devices (with mqtt support)
We will be making at least 10 videos related to AWS IoT core. Just wait for updates and subscribe to our channel.
Thats what AWS Greengrass is for. Also don't reinvent the wheel, AWS shadow device services handles holding last known state of device with updates ad updates/accepted
When I send data at 30-second intervals, only the first piece of data is sent and no more data is sent afterwards. But when the delay is set to one second, the data is sent normally. Why does this happen?
Great video and excellent explanation
Have a question about the certificate. Do I have to update the code on the EDP32 to make it work?
Yes update all the certificates
Thank you
nice video, thanks for sharing I following you...
Fantastic
Hi, Please make tutorials on Device provisioning service (DPS) using ESP32 & AWS.
Nice video! I manage to make it work following your instruction. Could you make a video on how to add the data to dynamodb using your code?
Bro simple SNS bus
Can you tell how to send these data to react web page ?
it will connected to iot aws but it will not connecting to connected to aws what can i do know
@How To Electronics : My client id is getting changed, because of that my communication is not getting established
Hello, can you make vidio water flow with iot cloud, please
hi i want use this android phone but how use it? please explain link or video. thanks...
Hi, you have a subtle problem in your code which could lead some students to problems. You declare your byte buffer as "char jsonBuffer[512]". That won't work by default. The MQTT payload size limit is hardcoded to 128 bytes in the MQTT library you are using. IF you want to use a larger buffer size for a bigger payload to publish then you would need to change the constant in the relevant header file in the MQTT library. If the user's payload exceeds 128 bytes in your 256 byte buffer, the device will connect but no payload will be delivered to AWS IoT Core
I have done all the steps but it is not connecting to aws iot . In output box it's showing like... Connecting to Aws Iot............................., what to do bro
I got problem that output is Connecting not connected
thanks you save us
Public key for what
Do you know what can I do if from AWS MQTT test is not possible send the sub message to the ESP?
You have a subscription option on your device in most ESP sketches. Simply subscribe to a topic then use a republish function from lambda or republish directly to your topic on IoT Core
how to get Gerber file?
I can not connect to AWS, where should I save the secrets.h file, And should I save the secrets.h file like as it is (all small letter) or must the s be a capital letter S. as on your discription?
Secrets.h is a separate file to add into the project, so your Arduino screen would have two file tabs (Arduino-->Sketch-->Add file) . Capitalization doesn't matter just keep the name consistent between the invoking file and the header file.
tysm
Successfully connected to iot etc. But mqtt sub and pub do not do anything?
Could you find a solution to it? pls share if u did...
My esp32 board is hangging at Connecting to AWS, could you help me out? It cannot connect to AWS IoT Core, only display Connecting to AWS......
having the same problem would like help as well if anybody could find a solution
Same Problem here too, mine is connecting to the wifi but not AWS. So presuming I've initialised it wrong somewhere. If anyone had this issue and subsequently managed to fix it, let us know 🙂
Usually this is caused by incorrect certificates. First step is to check the monitor tab in AWS IoT core to see if your device is even pinging aws, if not its likely a bad endpoint, also make sure your certificates are created in the same region as your current IoT Core console. After that make sure you have attached a policy to your certificates. Make sure your certificates are activated. Finally make sure port 8883 is not being blocked by your network admin.
It seems AWS does not have the same user interface anymore and I am really struggling to get esp32 connected to IOT Core. Any updated explanation?
Nevermind, it seems it is just superficial menu Changes, will try again
AWS connection just keep trying and not connecting, I did follow all steps to the letter. Any Advice?
Hi. I successfully connect to AWS IOT send and receive messages, but when I try subscribe a ESP32 to another ESP32 topic it stuck after sending one message. Could somebody suggest me how to subscribe to topic of another MQTT client
I replaced resource ARN path with * sign, as you wrote and it works :-) Thanks
error: 'class WiFiClass' has no member named 'mode'
WiFi.mode(WIFI_STA); I am getting this error, please help!!!
usually this means you have set your device incorrectly in the arduino environment
@@SteveOnIoT can you suggest the correct way?
Tutorial Doesn't work anymore because AWS changed resource ARN. Please update
Thats the problem. AWS keeps changing something after every few months.
@@HowtoElectronics Thank you for responding but that still doesn't help me :(
@@shoreydesigns3064 Hello just had a confirmation. The tutorial is still working fine. Just replace the resource arn with * . The * sign will allow everything to work.
mam it is showing no such file or directory for secrets.h
There are two codes in website. One with secrets.h. Copy the code and create a new tab and paste it there.
@@HowtoElectronics I went to sketch then add file and then pasted it there... still it is showing that error
@@HowtoElectronics is there any other method to do it??
@@ssaikumar6409 : Getting the same issue here. How did you resolve this?
I am getting an error which says; No such file or Directory for "secrets.h". Are there more steps involved in this?
Read the whole article again. There is another file called secrets.h that you need to create on another tab.
How much u paying for aws?
You will get 1 year for free
@@HowtoElectronics but i mean you have to enter your credit card number upon registering?
Wow, this is extraordinary content. I had the pleasure of reading something similar, and it was truly phenomenal. "Mastering AWS: A Software Engineers Guide" by Nathan Vale
Nice explained, Madam where to find #include which you mentioned at secrets.h
wifi.h is not working
any update ?
