Log data to ThingSpeak
To get an historical view of our data (maybe to see some trends) we need to log our data. In this example we'll use ThingSpeak as a host to log our sensor data. They provide some nice graphs and a generous free tier. Check out the tutorial below and log your CO2 and TVOC data every 10 seconds to ThingSpeak.
⚠ Note A hardcoded ThingSpeak URL is fine for the moment, we'll make it configurable in a next exercise
