The Internet of Things (IoT) has vastly extended the ways in which we can leverage digital technology with smart devices that can enhance our lifestyles. However, this exciting new technology can only advance with the help of suitably trained tech professionals with the crucial IoT knowledge and skills to develop and deploy it. With their help, we can look forward to a continued flow of new applications that will be transformative for numerous industries. Without it, IoT will remain a fascinating technological concept.

It requires an in-depth understanding of software and hardware to integrate the sensors, actuators, and communication modules that form the fundamental foundations of an IoT system. For example, devices like thermostats, heating, and lighting systems and security cameras in a typical “smart home” system must be designed to communicate seamlessly to ensure a cohesive, automated environment.

Developing Applications for the Internet of Things

Ensuring system architectures that are reliable, scalable, and secure requires an understanding of suitable network protocols; the rules applied to machine-to-machine communication using limited bandwidth. These are widely used for wearables like smart watches and remote monitoring of biodata. Other requirements include expertise in:

  • Programming Languages: Those most commonly employed in developing IoT applications include Python, Java, C, JavaScript, and PHP. 
  • Development Frameworks: The term refers to a collection of tools and library objects that can help developers create applications more efficiently and quickly. Those used in IoT applications include Amazon Web Services (AWS), Microsoft.NET, and Node-RED, a tool for wiring hardware devices together. There are also open-source options like Zetta and ThinkSpeak.
  • Machine Learning and Data Analytics: Both technologies have pivotal roles in developing applications for the Internet of Things. Their integration enables developers to create applications that can respond to user input while adapting to changes in their behaviour. One working example is the “Smart City” scenario in which traffic management systems employ IoT technology to analyse sensor data to predict traffic flows and adjust signal timing to minimise congestion.

The Deployment of IoT Applications

Developing an IoT app is only the beginning. After testing and debugging, the next step is deployment and field testing. Ensuring systems function as intended in a real-world environment also requires specialist knowledge. IoT applications employ communication technologies like Wi-Fi and Bluetooth. Tech professionals should be familiar with these and their benefits and limitations.

Monitoring and maintaining Internet of Things applications includes over-the-air (OTA) updating to ensure the system firmware remains up-to-date, secure, and enabled to meet the evolving requirements of the user.

IoT in Action

People are often surprised by the extent to which IoT technology has infiltrated and enriched our lives. Among the many industries that now enjoy its benefits, one is of particular importance to everyone:

In agriculture, smart sensors now monitor moisture levels in the soil, weather conditions, and plant health to provide farmers with a continuous flow of data that helps them take the necessary action to optimise crop production.
