In several cases, we are best off focusing on the RESTful protocol while working with the IoT devices. This allows us to simplify the exchange between the components of the system and helps us to expand the system of exchanging information in the future. Moreover, this library supports Python 2.7.9 and above or 3.5 and above.
This tendency will impact a wide range of industries, as well as our personal life. It improves the safety of connected cities, reduces the cost of asset tracking, personalizes healthcare and energy consumption more efficiently. With so many devices now connected to the internet, it’s no wonder that courses on the topic are in high demand. Whether you’re looking to learn about the basics of the Internet of Things or want to delve deeper into the topic, check out the IoT course available online. In metropolitan areas, noise and air pollution levels increase which needs addressing urgently. Therefore, one can monitor air and noise pollution levels using an IoT-powered air and noise pollution monitoring system.
As we will learn, choosing the appropriate method is all based around how and from where you intend to start your script and whether your code requires elevated permissions. You may have noticed that there is a package called colorzero (this is a color manipulation library) that we did not install. Gpiozero (version 1.5.0) has a dependency on colorzero, so pip has installed it for us automatically. Next, we will see how to install and manage Python packages in a virtual environment using pip. As a Python developer, we use Python virtual environments to sandbox our Python projects so they will not adversely interfere with system-level Python utilities or other Python projects.
In this article, we will explore the benefits and drawbacks of both Lua and Python and help you determine which language is the best choice for your IoT project. This project is beneficial mostly for huge car parking areas in the public places, most of the places in the cities and the public places who are facing a big issue regarding with the vehicle parking. It’s good to know, that Micropython supports many other different boards, includes running on Windows/Linux. Here are a few more exciting IoT projects that beginners can add to their portfolios.
MicroPython imposes many restrictions compared to regular Python; however, in general, we can easily write the necessary functionality on the client-side and execute it effectively on ESP microcontrollers. The primary objective of running Python on an IoT device that pops up in mind is grabbing the Raspberry Pi from the table. Python is pre-installed in the operating system, and the only objective left for us is to write the coding script. Some of the many benefits of working with Python for IoT devices are a large number of libraries for all types of platforms and the speed it offers at which we can develop the code.
Also, in the case of traffic control, there is effective Internet Of Things projects to simplify the parking or traffic management issues. Lastly, with the help of sensors and the ability to think out of the box, IoT projects can bring ease and save lots of lives and property in case of emergencies may it be natural (floods) or man-made. In the dynamic world, IoT is spreading everywhere, and you can take up any of the above ideas and come up with something that will serve mankind’s lifetime. Nowadays, the air quality is inferior in almost all metropolitan cities due to air pollution. Due to this human health is getting deteriorated and a lot of diseases have broken out.Air pollution monitoring systems using IoT can help in measuring air quality by leveraging the internet. In this project, LCD will display air quality in PPM constantly to monitor it regularly while saving essential logs for future usage.

The population is growing rapidly, so our demands and which agriculture is leveraging IoT to enhance productivity.
There will come a time when you have developed an awesome IoT project and you want it to run automatically every time you start your Raspberry Pi. Here is one simple way to achieve this using a feature of cron, the Unix scheduler. If you are not familiar with the basics of cron, search the web for cron tutorial—you’ll find heaps of them. Since we are using the virtual environment’s Python interpreter, we are still sandboxed to our virtual environment and any Python packages we installed are available. The most common way of running a Python script is from within its virtual environment and with the permissions of the currently logged in user.
Getting Started with The Raspberry Pi Pico – Blinking a LED on Pico Using MicroPython
Next, in Chapter 2, Getting Started with Python and IoT, we will jump straight into Python and electronics and create an end-to-end internet-enabled program that can control an LED over the internet. We will take a look at two alternative ways of flashing an LED using the GPIOZero and PiGPIO GPIO libraries before connecting our LED to the internet by using an online service, dweet.io, as our networking layer. Before we can start working with Python GPIO libraries and controlling electronics, one task we need to perform is to enable the GPIO interfaces on your Raspberry Pi. Even though we have installed Python packages for GPIO control, we have not told Raspbian OS that we want to use the Raspberry Pi’s GPIO Pins for specific cases. Let’s start by learning how to run a Python script with root user permissions. Let’s briefly turn our attention to the alternative ways that we can execute a Python script.
This is a project which uses esp8266 and arduino UNO along with ultrasonic sensor to detect the distance and send it to blynk mobile app and thingspeak channel. From now on, you will be able to send python files to your device and get full control on your device from the great Micropython abstraction. If you enter this article https://traderoom.info/ — you are probably a programmer that has some coding experience with Python. Moreover, you’ve probably also come up with ideas over the years that could improve the quality of human life using smart devices(IoT). IoT (Internet Of Things) refers to the devices which are connected through the Internet and exchange data.
- It is one of the best ways to save energy as sensors send signals to the microcontroller in case of any activity on the road resultantly turning on the streetlight.
- Microsoft has released a new open-source extension for IoT to extend the capabilities of Azure CLI 2.0.
- In this book, we will be using a virtual environment tool known as venv, which comes bundled as a built-in module with Python 3.3 and above.
- For now, we are just going to check for and install two GPIO-related packages.
- For this example, you will need a device like an Nvidia Jetson that has an onboard GPU for quickly doing inference on images taken from a video stream.
- These projects develop smart systems that aim to simultaneously make our lives safe, secure, and convenient.
The extension of CLI allows an Azure service to complement Azure CLI by providing users access to additional capabilities specified to services. One of the most popular connection methods for IoT devices is MQTT, and it is a protocol used for effective implementation with Python. The complete procedure of development is carried out on a working computer, and then it is compiled and saved in the memory of an ESP8266 or ESP32 microcontroller. We can download the firmware from the website and install it with the help of esptool, not forgetting to format the board before installing it.
Using Python for software development
The integration of images with older 2.7 versions of Python is straightforward. The Python client library called Eclipse Paho MQTT implements versions 3.1, 3.1.1, and 5.0 of the MQTT protocol. Another advantage of using Lua as an embeddable language is its performance. Lua is a highly efficient language that is optimized for speed and memory usage. This makes it ideal for use in resource-constrained environments, such as embedded systems.
If any movement is detected, the sensors will alert the microcontroller, which will switch on the street light. It can also track predicted power use and detect any light faults, sending the information to an IoT monitoring system for resolution. One of the main advantages of using Lua as an embeddable language is its simplicity. It is also highly customizable, which makes it a popular choice for developers who want to create custom applications.
- This project is beneficial mostly for huge car parking areas in the public places, most of the places in the cities and the public places who are facing a big issue regarding with the vehicle parking.
- If you only need a low-powered microcontroller to perform the task, it probably makes sense to use that rather than spending money on an SBC with computing resources you don’t need.
- As Python developers, we must take care not to disrupt the global Python installations as this can potentially break system-level utilities.
- It connects to your PC via USB, giving you a USB flash drive to save your Python scripts and a serial Python prompt (a REPL) for instant programming.
- A microcontroller-based circuit is fitted in the mining worker safety helmet which tracks the environment of the mining site and evaluates the safety parameters.
In this section, we will discuss how Python interacts with your operating system installation and cover the steps necessary to set up and configure a Python development environment. In addition, as part of our setup process, we will clone the GitHub repository that contains all of the code (organized by chapter) for this book. We will now turn our attention to a very important Python concept, the Python virtual environment, which is the way we isolate or sandbox our own Python projects from the global installation. In this section, we will find out which versions of Python you have installed on your Raspberry Pi. As we will discover, there are two versions of Python that come pre-installed on Raspbian OS. Unix-based operating systems (such as Raspbian OS) typically have Python version 2 and 3 pre-installed because there are operating-system-level utilities built with Python.
In the above snippet of code, we have imported the Pin module from the machine library along with the time module. We have then created an object of Pin and execute some functions on it. The PyBoard is considered a compact as well as a powerful electronics development board. The PyBoard connects to the PC through USB, providing us with a USB flash drive to store the Python scripts and a serial Python prompt (a REPL) for instant programming. Due to extreme traffic on roads, it is almost impossible to find a vacant parking spot without any hitch. The IoT-based smart Parking System is the solution to tackle all the parking issues.

Can we use Python for IoT projects?
Python becomes a great choice when it comes to IoT. We can either use it for the backend side of development or the software development of devices. Moreover, Python is available to work on Linux devices, and we can make use of MicroPython for microcontrollers.
Python can be effectively used for programming IoT devices as well as developing the corresponding back-end. The speed of development, the low threshold for learning Python, and a large set of Python libraries make this programming language indispensable for IoT. Lua and Python are both dynamic, high-level programming languages that are popular choices for IoT projects. Lua was developed in 1993 by a team of Brazilian programmers and is used extensively in video games, web applications, and embedded systems. Python, on the other hand, was developed in the late 1980s by Guido van Rossum and is used in a wide range of applications, from web development to scientific computing. The Internet of Things (IoT) is an ever-expanding network of interconnected devices that are revolutionizing the way we live and work.
In the following tutorial, we will understand the use of Python in programming Internet of Things (IoT) devices and create a backend for them to work. Lua’s lightweight nature and ability to be embedded into other programs make it a popular choice for resource-constrained IoT devices and edge gateway applications. However, its single-threaded nature can limit its performance in more complex applications. While Lua has many advantages as an IoT programming language, it also has some drawbacks. Edge gateways are devices that perform data filtering, aggregation, and transformation.
If necessary, you can install the previous version of Python 2.7 for past compatibility. The first thing that comes to mind about running Python on an IoT device is grabbing your beloved Raspberry Pi from the table. Python is pre-installed in the operating system and the only thing left is for you to write your own script.
This section relates to venv, which we have been using in this chapter, and will apply to virtualenv but not pipenv, which we listed as alternative virtual environment tools. The example is also specific to a Raspbian OS and is typical of a standard Unix-based OS. In this section, we learn how to install and manage Python packages in a Python virtual environment you created and explored in the previous section.
We are offering some attractive and easy to do IoT based projects for the students. Founded in 2008, the infrastructure monitoring expert serves customers in more than 70 countries, with a network of global partners to jointly drive safety in mining, construction, rail and structural health. The controllers, available in a wide range of computing power and budgets, can be chosen for your IoT system – from the fast Raspberry Pi 4 Model B 8GB to the smallest Raspberry Pi Zero, all supporting Python.
We have now seen that there are two Python versions available by default on Raspbian OS, and made mention that there are system-level utilities that are written in Python that reply on these versions. As Python developers, we must take care not to disrupt the global Python installations as this can potentially break system-level utilities. If you are an experienced Python programmer, you may be able to discern whether a script is written for Python 2 or 3, but it’s not always obvious by simply looking at a piece of code. Many new-to-Python developers experience frustrations by mixing up Python programs and code fragments that are meant for different Python versions. Always remember that code written for Python 2 is not guaranteed to be upward-comparable with Python 3 without modification.
