Internet of Things with Python

Overview of this book

Internet of Things (IoT) is revolutionizing the way devices/things interact with each other. And when you have IoT with Python on your side, you'll be able to build interactive objects and design them. This book lets you stay at the forefront of cutting-edge research on IoT. We'll open up the possibilities using tools that enable you to interact with the world, such as Intel Galileo Gen 2, sensors, and other hardware. You will learn how to read, write, and convert digital values to generate analog output by programming Pulse Width Modulation (PWM) in Python. You will get familiar with the complex communication system included in the board, so you can interact with any shield, actuator, or sensor. Later on, you will not only see how to work with data received from the sensors, but also perform actions by sending them to a specific shield. You'll be able to connect your IoT device to the entire world, by integrating WiFi, Bluetooth, and Internet settings. With everything ready, you will see how to work in real time on your IoT device using the MQTT protocol in python. By the end of the book, you will be able to develop IoT prototypes with Python, libraries, and tools.

Summary


In this chapter, we combined many cloud-based services that allowed us to easily publish data collected from sensors and visualize it in a web-based dashboard. We realized that there is always a Python API, and therefore, it is easy to write Python code that interacts with popular cloud-based services.

We worked with the MQTT protocol and its publish/subscribe model to process commands in our board and indicate when the commands were successfully processed through messages. First, we worked with the PubNub cloud that works with the MQTT protocol under the hoods. Then, we developed the same example with Mosquitto and Eclipse Paho. Now, we know how we can write applications that can establish bi-directional communications with our IoT devices. In addition, we know how we can make IoT devices communicate with other IoT devices.

Now that we are able to take advantage of many cloud services and we worked with the MQTT protocol, we will learn how to analyze huge amounts of data, which is...
