Virtuabotix DHT11 Temperature & Humidity Sensor


Tired of getting heavy metal poisoning from waving thermometers around? Done gauging humidity by the time it takes for your tongue to dry as you wag it wildly through the air? If you answered yes to any of these questions then this is the product for you; though it may be advisable that you seek immediate psychological/medical attention.*

The DHT11 is a robust little one-wire device that can measure both temperature and humidity; it is perfect for almost any indoor or outdoor use! It has been used in thousands of projects already, what awesome project will you do with it? You can measure your homes ambient air temperature & humidity, turn on fans to vent a room or to keep your server racks humidity levels down. You can turn on heaters or air conditioning systems with a relay on your Arduino Uno, or you can log your moister and temperature readings for later analysis. Whatever you do, we can't wait to hear about it, so be sure to share your experience with us, and the open source community once your project is complete!

*Note: The DHT11 is not a cure for heavy metal poisoning, if you believe that you are suffering from any form of heavy metal poisoning related to the act of recklessly waving thermometers around (or other such unintelligent behavior) we recommend you contact your nearest poison control center immediately.
