That’s an Arduino wired up to a DHT22 temperature and humidity sensor ($9.95 from The Robot Shop). Using the wiring diagram helpfully provided by Adafruit I connected the DHT22 to the Arduino, with ...

DHT22 Library DHT22 is a sensor device that measures the temperature and humidty. DHT22 Library aims to create a light version of the Arduino IDE DHT22 libraries. The purpose of this repository was to ...

This is a custom "driver" library for Arduino IDE for DHT22 sensor... although to be fair I merely just "reformatted" the existing funcions in the Adafruit library. dht22.ino is a "main" program to ...

Seeking a quick-and-dirty success, and beaten down by hours of hacking away for naught, I pulled a DHT22 sensor out of the eBay bin, and cloned Adafruit’s DHT library.
