Everything you Need To Know About The IoT Stack

by | Feb 26, 2019 | IoT Software Platforms

The IoT technology refers to a network of objects connected to the internet including the likes of vehicles, devices, and buildings.

Sensors and electronic components are built into objects to enable them to collect and transfer information to your cloud database. The IoT technology allows objects produced by your company to be remotely detected and controlled through the existing network infrastructure.

This helps in creating the opportunity for direct integration between your digital and physical worlds.

What Is An IoT Stack?

Traditionally, the adoption of innovative technologies is accelerating after the definition of frameworks, languages, protocols, and standards. Each layer of a technology stack must integrate and communicate with the other layers of the stack. With the evolution of the stack, it becomes easier and inexpensive for developers to create new services and products.

The IoT stack is capable of rapid development. This stack consists of three technological layers: sensors, microcontrollers, and Internet connectivity, and service platforms.

  • Layer 1 – Sensors are embedded in objects or the physical environment to capture information and events.
  • Layer 2 – Internet connectivity and microcontrollers share information captured by sensors within your IoT objects and act on the same information.
  • Layer 3: Through the analysis and aggregation of data, service platforms meet the needs of your customers. These platforms also control the end-to-end experience of your IoT products and allow your customers to set system rules and update the firmware.

Layer 1 – Sensors

They have been used for many years in many industrial contexts such as health care, manufacturing, aviation, and automotive.

Now, sensors are so small and inexpensive that they can be integrated into any device you use personally and professionally. The sensor layer of the IoT technology stack continues to expand as they are added more and more to new products and services.

Layer 2 – Microcontrollers and Internet Connectivity

The second layer of the technology stack of the Internet of Things allows for local storage, data processing and Internet connectivity.

The Internet of Things needs internet connectivity to send the collected data to your cloud database. Since some sensors generate over 10,000 data points per second, it’s a good idea to pretreat the data locally before sending the same to your cloud database.

By analyzing, extracting, and synthesizing the collected data before sending it to your cloud database, you reduce the amount of unnecessary data you send and store on your cloud database, saving you money on your cloud database.

The microcontroller is a small computer embedded in a chip. It helps your IoT store pre-process collected data before synchronizing with your cloud database.

Layer 3 – Service Platforms

The first two layers of the IoT Stack embed microcomputers and sensors into your IoT device, but IoT products profit particularly from the service platform layer.

This layer adds value to your customers by automating processes and providing rich data analysis. Your cloud application combines data collected from many IoT sensors with other data in your business (or your customers’ data) to generate information driving business value.
