Arduino Weather System - Ep2: Arduino and AWS Cloud

#homeAutomation #DIY #Arduino

This video is the second episode in the "Arduino Weather System" series. It builds on the previous one and continues forward by pushing the temperature & humidity data received through the DHT11 sensor, onto an AWS IoT account.

0:20 New VSCode project and code to connect to WiFi
2:16 Compiling and uploading code to the ESP8266
2:46 Wiring the ESP8266 to the Arduino Uno board
3:07 Wiring schema
4:10 Moving password and other sensitive information to "secrets.h" file
5:28 Sending data through an MQTT topic
7:20 Lambda function that persists data into a DynamoDB table
10:16 AWS IOT Rule that invokes the Lambda function
12:32 Taking the build outside for a last test

I start by showing the WiFi module used to allow our weather station to go online: it's a programmable module called "ESP8266 ESP01". I then create a new project on VSCode using the PlatformIO extension and dive right away into writing the code that does the following steps:
→ Connect to WiFi
→ Establish a connection to AWS IoT's MQTT topic
→ Send data through the topic

I then connect the WiFi module to the Arduino board and test that it sends the data over. Once that confirmed, I create a Lambda function that handles the received data by saving it into a DynamoDB table.

I will add more sensors as we progress.
