History of IoT

The fascinating tale of IoT technologies begins in the visionary 1980s, when innovative minds pondered the prospect of imbuing everyday objects with sensors and intelligence. It all started with a group of enterprising university students who embarked on a mission to revolutionize a Coca-Cola vending machine. Their audacious goal? To empower the machine to remotely track its contents. However, the technology of that era proved cumbersome, and progress remained constrained.

Fast forward to 1999, when a computer scientist by the name of Kevin Ashton introduced the term that would define this groundbreaking domain – the “Internet of Things” or IoT. At the time, Ashton was working at Procter & Gamble and conceived the idea of affixing radio-frequency identification (RFID) chips onto products, thereby enabling their seamless tracking throughout the supply chain.

Father of IoT Kevin Ashton

Sometimes Kevin Ashton is also known as the Father of IoT or Inventor of IoT. To capture the attention of executives and secure support for his novel concept, Ashton cunningly integrated the then-buzzing term “internet” into his proposal. This ingenious move paid off, and the phrase “Internet of Things” became indelibly etched into the technological lexicon.

With each passing year, the momentum of IoT technology accelerated, captivating the imagination of the public and igniting a fervor for connected devices. In the year 2000, a milestone was reached when LG unveiled the world’s first smart refrigerator, a marvel of innovation that hinted at the exciting possibilities to come. As the world stood on the precipice of a digital revolution, 2007 marked a pivotal moment with the introduction of the very first iPhone. This iconic device not only redefined the way people interacted with technology but also served as a catalyst for IoT’s meteoric rise.

The march of progress continued, and by 2008, the number of connected devices had already surpassed the global human population, signaling a transformative era where the synergy of devices and the internet would shape the fabric of daily life.

Application of IoT

Fueling the ambition for autonomous mobility, 2009 witnessed the commencement of Google’s audacious trials of driverless cars, a testament to the boundless aspirations of IoT to redefine transportation. In 2011, Google’s Nest smart thermostat emerged as a game-changer, empowering users to remotely control their central heating. This innovation epitomized the fusion of IoT, convenience, and sustainability, bringing environmental consciousness to the forefront of technological advancement.

The tale of IoT is an ongoing narrative, continually unfolding with each passing day. As the world embraces an interconnected future, the legacy of IoT’s history serves as a reminder of human ingenuity and the relentless pursuit of progress that continues to shape our world. With boundless potential and limitless horizons, the IoT revolution shows no signs of slowing down, offering a tantalizing glimpse of the possibilities yet to be realized.

How does IoT work?

The Internet of Things (IoT) is a network of physical objects or “things” embedded with sensors, software, and other technologies that enable them to collect and exchange data over the Internet. These connected devices can interact with each other and with centralized systems to perform various tasks, monitor conditions, and automate processes. Here’s how IoT works:

Sensors and Actuators: IoT devices are equipped with various types of sensors, such as temperature sensors, motion sensors, humidity sensors, cameras, and more. These sensors gather real-world data from the environment or specific objects. Additionally, some IoT devices may have actuators, which are components that allow the device to take action based on the data it receives. For example, an IoT thermostat can sense the temperature and actuate heating or cooling systems accordingly.

Data Collection: The sensors on IoT devices continuously collect data from their surroundings. This data can be anything from environmental conditions (temperature, humidity, air quality) to user behavior (usage patterns, preferences) and more. The data is then processed and sometimes filtered before being sent to the next step.

Connectivity: IoT devices require some form of connectivity to transmit the collected data. They can use various communication technologies such as Wi-Fi, Bluetooth, cellular networks, Zigbee, LoRaWAN, or other wired and wireless protocols to connect to the internet or to a local network.

Data Processing and Analysis: Once the data is transmitted to the cloud or a centralized system, it is processed and analyzed. Cloud computing is often used for this purpose due to its scalability and processing capabilities. Here, the data may be combined with data from other sources, and machine learning algorithms might be applied to derive valuable insights or make predictions.

 

Decision-Making and Action: After the data is analyzed, the IoT system can make intelligent decisions or trigger specific actions based on the insights gained. For example, an IoT system monitoring a factory’s equipment might detect an anomaly indicating possible machinery failure and automatically send a maintenance request to prevent downtime.

User Interface and Control: End-users can interact with IoT devices and systems through various means, such as mobile applications, web interfaces, or voice commands. This allows users to control and manage their IoT devices remotely, set preferences, view data analytics, and receive alerts or notifications.

Security and Privacy: As IoT devices handle sensitive data and interact with physical objects, ensuring security and privacy is crucial. Encryption, authentication mechanisms, and regular firmware updates are employed to safeguard IoT devices and prevent unauthorized access.
