Virtuabotix DHT22 Digital Temperature/Humidity Sensor
Description: We brought you protection from the dangers of heavy metal poisoning; we taught you how to keep your tongue comfortably inside your mouth while gauging the humidity of your surroundings; but still you demanded more... and, we listened. The bigger, better DHT22 not only replaces the DHT11, but we have carefully written a library for it that is 100% compatible with code written for the DHT11 library (of course you have to call and declare a dht22 instead of dht11). The DHT22 gives resolution of up to 0.1 % humidity and 0.1 degrees C (accuracy is +- 0.5 C); Which makes it perfect for applications that require a little more precision to get the job done. In addition the ranges of operation are raised to 0% to 100% humidity, and -45 to 125 degrees C. The DHT22 is a robust little one-wire device that can measure both temperature and humidity; it is perfect for almost any indoor or outdoor use and can stand up to a lot more of the elements than its cousin the DHT11!
