Hardware configuration
The hardware connections for this project are actually quite simple. We have to connect the
DHT11 sensor, the pressure sensor, and the part responsible for the light level measurement.
The following picture summarizes the hardware connection:

).
First, place the DHT11 sensor and the BMP sensor on the breadboard. After that, connect
the Arduino Yun +5V pin to the red rail on the breadboard, and the ground pin to the blue
rail.
Then, connect pin number 1 of the DHT11 sensor (see the schematic) to the red rail on the
breadboard, and pin number 4 the blue rail. Also connect pin number 2 to pin number 8 of
the Arduino Yun. To complete the connections of the DHT11 sensor, connect the 4.7k Ohm
between pin number 1 and 2 of the sensor.
