Serverless IoT Metrics Dashboard

Goal of this project is to create Serverless & code-less (as possible) solution for gathering data from IoT sensors to the cloud without Lambda functions.

Prerequisites

• AWS Account
• Raspberry PI with SenseHAT
• Node.js on dev machine
• Python & SSL module on Raspberry

Running the project

git clone https://github.com/RafalWilinski/serverless-iot-metrics-dashboard
cd serverless-iot-metrics-dashboard

# Create X509 Certificates
./create-certificate.sh

# Deploy infrastructure to AWS
cd backend && serverless deploy && serverless create-appsync

# Start collector on Raspberry PI
cd collector && python collector.py -e <YOUR_AWS_IOT_URL>

# Run dashboard on master computer
cd dashboard
mv .env.example .env

npm start

Dashboard demo

Structure

backend - contains Serverless Framework based infrastructure

collector - script gathering metrics from Raspberry Pi connected to the cloud

dashboard - frontend for representing the data

Data flow

1. Python based collector gets metrics from SenseHat and pushes them via MQTT protocol to AWS IoT
2. AWS IoT uses IoT rule to push the data to AWS DynamoDB
3. Data from DynamoDB can be queried via AWS AppSync from React app
