Hardware & software requirements
For this project, you will of course need the Arduino Yun board. You will also need a
DHT11 (or DHT22) sensor, along with a 4.7K resistor, for humidity measurements.
For pressure & temperature measurements, I used a BMP085 sensor on a breakout board.
You can also use the newer BMP180 sensor, which works with the same library.
For light levels measurements, I used a photocell with a 10K Ohm resistor. Finally, I used a
breadboard and some male-male jumper wires.

On the software side, you will need the Arduino IDE 1.5.x in the latest version (in Beta when
this article was written):
You will also need the DHT library:
