The whole project is based on the Arduino platform, so you will need an Arduino board. I really recommend using the Arduino Uno board for this project, as it is one of the only board that is compatible with the CC3000 library at the time this tutorial was written.
Then, you need the Adafruit CC3000 breakout board to make the WiFi communication, and the DHT11 temperature & humidity sensor (you can also use the DHT22 or the AM2302 sensors which are almost identical to wire up but higher quality). You also need a 10K Ohm resistor to be used with the DHT sensor.
Finally, you need a breadboard and some jumper wires to make the connections between the different parts.

DHT11 sensor
The DHT sensor is quite easy to connect: just plug the pin number 1 to the Arduino’s 5V, pin number 4 to GND, and pin number 2 to Arduino pin 7. Finally, put the 10K resistor between the sensor pins number 1 and 2.
CC3000 Breakout Board
The hardware configuration of the CC3000 breakout board is relatively easy. Connect the IRQ pin of the CC3000 board to pin number 3 of the Arduino board, VBAT to pin 5, and CS to pin 10.Then, you need to connect the SPI pins of the board to the corresponding pins on the Arduino board: MOSI, MISO, and CLK go to pins 11,12, and 13, respectively.
Finally, you have to take care of the power supply: Vin goes to the Arduino 5V, and GND to GND.
The following picture summarizes the hardware connections:
