What is LoT and how is it developed? We live surrounded by smart devices. From the thermostat in the dining room to the clock that measures the quality of sleep. Indeed, all this is part of an ecosystem that is growing at great speed: the Internet of Things, or IoT (Internet of Things).<\/strong> <\/p>

Now, how do these applications work? What processes are behind it for a sensor to be able to talk to a mobile app or an automated system? This is precisely where the development of IoT applications comes into play, a discipline that combines hardware, programming, usability and connectivity.<\/strong> <\/p>

For agencies such as wwwarcelona<\/a>, with an orientation towards strategic and digital design,<\/strong> understanding and participating in these environments is therefore key to offering connected and competitive solutions in today’s<\/strong> market.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

How does an IoT application work?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

An IoT application is not just a conventional app. Rather, it is a piece within a larger system that connects the physical world with the digital one. <\/span><\/p>

Basic architecture<\/h3>

Generally speaking, operation can be divided into three essential levels:<\/span><\/p>

  1. Smart device or node<\/b>: such as sensors, cameras, or boards such as Arduino or Raspberry Pi.<\/span><\/li>
  2. Cloud platform<\/b>: which collects, stores and analyzes the data that arrives from the devices.<\/span><\/li>
  3. User application<\/b>: this can be a website or a mobile app from which data is viewed or actions are controlled.<\/span><\/span>

    <\/p><\/li><\/ol>

    For example, a temperature sensor sends information to the cloud. The user then sees it in the app and can set up alerts or automatic actions. This <\/span>real-time data flow<\/b> is undoubtedly the essence of the IoT.<\/span><\/p>

    Communication between devices<\/h3>

    In terms of communication, IoT devices communicate through protocols such as MQTT, CoAP or HTTP, using technologies such as Wi-Fi, Bluetooth, Zigbee or LPWAN networks. Depending on the project, each use case determines which is the best option in terms of <\/span>power consumption, range and speed.<\/b><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    To understand how these applications are developed, you first need to know the fundamental blocks:<\/span><\/p>

    Sensors and actuators<\/h3>

    On the one hand, sensors collect information: temperature, light, movement, pressure, etc. On the other hand, actuators perform actions such as turning on a light or opening a valve. Together, they are the interface with the physical world. <\/span><\/p>

    Microcontrollers and embedded systems<\/h3>

    Platforms such as <\/span>Arduino, ESP32 or STM32<\/b> are used to control the sensors and manage the connection with other devices. So, this is the heart of the IoT system.<\/span><\/p>

    Connectivity<\/h3>

    Obviously, without an Internet connection, there is no IoT. Therefore, the choice between Wi-Fi, 4G, NB-IoT or LoRaWAN will depend on the location, battery need and data volume. <\/span><\/p>

    Cloud infrastructure<\/h3>

    Finally, a fundamental part is the <\/span>IoT backend<\/b>, which processes and stores information. Platforms such as AWS IoT, Google Cloud IoT or Microsoft Azure allow scalable and secure systems to be developed.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
