Objective

This project shows you how to build a fleet of IoT temperature sensors that you can use to answer potentially burning questions, like:

  • Do I trust thermostat reading on my wall?
  • Do different rooms in my house have similar cooling profiles?
  • What’s the relationship between how hot it is outside and how much electricity is used?

Part 1: Build a sensor, Publish the data

After this post, you’ll be able to:

  • Publish temperature sensor measurements powered by an Arduino
  • Read the sensor readings using the MQTT protocol
  • Create a mysql database to store the measurements
  • Write incoming measurements to the database

Things You’ll Need:
