Let's first see what components we need for this project. You will need the usual Arduino Uno board. Other boards such as Arduino Mega would work as well, but this project has not been tested with more recent boards such as Arduino Leonardo or Arduino Due.
You will also need a board that hosts the CC3000 Wi-Fi chip. I used the Adafruit CC3000 Wi-Fi board again, but you can also use an Arduino shield that hosts this Wi-Fi chip like the Adafruit CC3000 shield.
Note
Other boards or shields hosting the same Wi-Fi chip would work as well, but there are no guarantees and you might have to slightly change the code of the project.
For the temperature and humidity measurement, we are going to use a digital sensor, the DHT11. Note that you can also use the DHT22 sensor, which is more precise and works with the same library.
You can also use your own sensor for these measurements, or even two sensors, but you will then have to change the code accordingly. You will also...
