Chapter 3. Measuring the Temperature
Using Bluetooth
In this third chapter of the topic, we are going to use yet another technology for home auto-
mation purposes. We will use a very commonly used technology for sensors, namely,
Bluetooth. We are going to interface a Bluetooth module with Arduino, make some meas-
urements using Arduino, and transmit this data back to your computer via Bluetooth. To re-
ceive and display the data on your computer, we are going to use the programming lan-
guage Python.
The following are the major points we will see in this chapter:
• We are first going to select the different hardware components for the project, in-
cluding the Arduino board, the Bluetooth module, and the temperature and humid-
ity sensor. At this point, we will also install the different software components that
are required for the project.
• Then, we will actually build the hardware part of the project. To do so, we'll con-
nect the different components together using a breadboard and some wires.
• Right after the hardware assembly, we are going to build the Arduino sketch for
our project. At this point, we will be able to test our hardware to see whether all
the connections were made correctly.
• Finally, we are going to build a graphical interface based on Python that will auto-
matically measure the data and display it on your computer, all via the Bluetooth
interface.
