This is a basic weather station using a DHT11 sensor for temperature and humidity. The project uses iShield App for iOS devices, the Arduino reads the data from the sensor and then sends this information via Bluetooth to display it in the app.
The project uses the DHT11 and iShield Library for Arduino.
Here is more information about iShield.
I like to use Codebender to program Arduino but the code is also available on github.
