That’s what I did this week, as my wanderings into wireless data collection continue: Post the temperature and humidity from my little experiment to a table at data.sparkfun.com.
Here are the steps as things stand now:
- The sensor reads the data (as in my original post).
- The Ardunio formats a message and texts it with a Fona (wiring details here, updated code here).
- Instead of texting to Twitter, it now texts to a phone number I bought at Twilio for $1/month.
- Twilio then relays that data to my project server in the Amazon cloud as an http “POST” (deets on setting up a cloud server here).
- My project server parses the text message, composes a URL with the data, and hits the Sparkfun open data system with that URL (code for that is here).
This all happens in just a few seconds, every 20 minutes.
