+ODUINO ONE is a package of Arduino Uno R3 and LCD/Keypad/sensor.
+You can buy this item in this link.

+DHT11 Sensor (Humidity / Temperature sensor)
+[[http://www.micro4you.com/files/sensor/DHT11.pdf]]
+Connections are (V)oltage, (S)ignal, (G)round
+{{en:oduinoone:dht11-humiditytempvsg.jpg}}
+DHT11 uses one-wire communication and I connected it to the digital Pin#3 of Arduino.
+Also note that we should add a 10Kohm pull-up resistor on that pin.
+{{en:oduinoone:oduinoone_side.jpg?600|}}
+The example code shows the temperature, humidity and pressed keypad information on LCD.
+It also transmit that information to the host via USB.
+{{en:oduinoone:oduinoone_top.jpg?600|}}
+To compile this source code, you need to install the Arduino IDE on your ODROID board or PC.
+<code>
+$ sudo apt-get install arduino
+</code>
+I could run the Arduino IDE on ODROID with Ubnutu image.
+The connection node of Arduino USB is "/dev/ttyACM0" or "/dev/ttyACM1".
+To complete to compile this test code, you must install the library of DHT sensor.
+Download dht.cpp and dht.h from below link and copy them into "~/sketchbook/libraries/dht".
+[[http://playground.arduino.cc/Main/DHTLib]]
+I should restart the Arduino IDE after copying to use the library.
