I use a BMP085 and I get the temperature ( an 0% value for humidity) in the Temperature tab, and the pressure widget in the Meteo tab.

Instead of wiring 4 or 5 DHT22, on a distance up to 200 feet !! , I would suggest to use ESP8266 module with DHT22 wireless sensor, connected by wifi to your Raspi.
Much easier to install an less expensive the 200 feet wiring.
See "ESPEasy" also.
