Let's start with learning how to use sensors with Intel Galileo. In this section, we will develop an application with Intel Galileo. We pick the temperature and humidity sensors for application development because knowing the temperature of your house is the key to energy management. With temperature data, you can decide whether to switch on or switch off the heater or air conditioner in your home to save energy.

In order to get temperature data, we will use a new device: the Sensirion SHT11 Temperature and Humidity Sensor. We will connect this sensor to Intel Galileo's pinout to read temperature and relative humidity values. All the development will be done with the C programming language and Linux operating system, as mentioned earlier.

When we are finished with this section, you will have the knowledge to use pins on Intel Galileo and GPIO device files in the Linux filesystem. These methods can be reused for other sensors and devices...
