I did something similar using a DHT22 and a Photon. The DHT22 is neat because it also measures humidity and so you can report on both. Here are some suggested enhancements:
Publish your temperature data to Ubidots to provide a graph of temperature changes over time
Create a webpage that will publicly display the temperature
Add an LED to display the temperature visually
Update the page in 2 to allow you to remotely turn the LED on and off
1 and 2 are the simplest since they only require software updates.
