Perhaps a DHT22 sensor connected to a GPIO which gives humidity and temperature display on the home page.
While it might be neat to control solenoids based on temperature, it's not always wise to be automatically watering things in the heat of the day. That said I have a small green house which gets quite hot in the Aussie summer, so being able to open vents/switch on a sprinkler when a temperature threshold is reached could be a great use for this...I've done a bit with DHT22 and other RPi units....mmm, thinking of a plug in..
