Sends sunrise, sunset and air quality data for Seattle WA to Arduino IoT Cloud.
An Arduino can then grab this information from IoT Cloud and display it.
Learn more about this project (and corresponding Arduino sketch) on my blog at Regional Air Quality with Arduino Explore IoT Kit.
Server hosted on Heroku at https://sunrise-arduino-iot-cloud.herokuapp.com
- Sunset and sunrise calculated by suncalc library. No API needed.
- Air quality data (Ozone and PM2.5) comes from U.S. EPA AirNow API: https://docs.airnowapi.org
Example output from src/send.js script:
Setup heroku CLI on MacOS via brew tap heroku/brew && brew install heroku.
heroku login
Clone repo then run heroku git:remote -a sunrise-arduino-iot-cloud to setup remote to Heroku for deploying.
Create a local .env file by copying .envSAMPLE and then updating all the env vars.
heroku local # runs local server and loads .env vars
Run command that pushes data to Arduino IoT Cloud:
heroku local:run npm run send-sunrise
Add your config:
heroku config:edit
Then add:
