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 AM2302 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.
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.
The DHT sensor is much easier 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.
