Reads about 1 degree higher. Problems with polling every 5 seconds

DHT22 should support polling every 2 seconds. To be safe, I did this every 5 seconds and still had issues when every 4 or 5 readings it returned "nan", aka Not A Number, instead of the actual temperature and humidity reading. I'm using the Adafruit DHT library for Arduino. Temperature readings are accurate to 1/10th of a degree, so I expected decent accuracy, but it showed slightly high readings compared to several other sensors.

Pros
