I am developing a weekend project - mini weather station, trying new technologies along the way. Weather station is running on CHIP (a $9 step brother of Raspberry Pi - check out getchip.com) reads temperature from 1-Wire DS18B20 sensor every 30 seconds and sends it to AWS IoT over MQTT, where rule is configured to save temperature in the DynamoDB.

Frontend is going to be implemented on HTML5 + React.JS. It would request last temperature from serverless backend running on API Gateway + several Labmda functions.

What's done

Weather station code is complete
AWS IoT rule set up, data is stored in DynamoDB
Deployment process is set up using serverless
One API - get_latest_weather() is implemented

What's left

Create frontend to show latest temp; figure out the best way to deploy it to S3
Set up S3/CloudFront
Configure custom domain
Add some charts to the frontend to show temperature over time
Add bunch more APIs to get historical data and list of available weather stations
May be throw in some tests
