Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
With only 3 wires: S_ignal, 5V and GND you can get infos which you can use to measure temp. and humidity. Price is very good and the sensor works fine. You can get the Temperature, % humidity and the Dew Point for the combination of Temperature and % Humidity. You can find lot of examples on internet. Just attach to Arduino download the library and start measure.
Cons:
Not measure under 0 Celsius
Other:
In addition, you don't need the pull up resistor which is shown in the sensor datasheet. Resistor is already installed. Practical
Bottomline:
Good sensor and cheap, i recommend it. You can use this product with 3.3V without problem.
