It is very simple to set up two separate sensors for this, however I used one sensor that reads both humidity and temperature. DHT sensors are cheap and able to read both temperature and humidity. They have four pins and connect as follows:

VCC (3V-5V power) Data out No connection Ground

Attach a 10K resistor between the VCC and Data lines as well. A diagram is displayed above.

In order to use the DHT sensors you will need to download the DHT library. Here is one from Adafruit. In order to use it, download the DHT.cpp and DHT.h files and put them in a folder called "DHT" in your arduino "libraries" folder.

Here is a sample code from adafruit for your DHT sensor:
