DHT11LIB V2S0A Is an Arduino Library designed specifically to work with the DHT11 Sensor, completely re-written to be Arduino 1.0 and Versalino Compatible. It features built in unit conversions, easy to use readouts, and automatic Dew Point calculations.

PURPOSE: Measure and return temperature & Humidity. Additionally provides conversions.

We put a lot of work into our hardware and software. All we ask is that you share it so that others can benefit from our free libraries.

    I am interested in it. Could you explain with a real example how does it work, other components (hardware and softare) needed?

      The DHT11 communicates using Pulse Wave Modulation over a single digital pin. As such it can work on just about any micro controller that can be programmed to parse the data out.

      As it stands there are two devices that I know of with verified functional libraries for the DHT11. One of them is this library for the Arduino/Versalino (any Arduino Compatible board will work just fine), and the other is for the Netduino (

      As long as you have a 5V rail and a Micro-controller you should be set to use this device, but be sure to let me know if you need any help getting started!
