IoT devices have sensors with the primary role of collecting useful data. Small-size sensors like accelerometers, pressure sensors, and others are key to collecting relevant real-time data on device parameters, environmental conditions, and user behaviors.
5) Reliable Data
The massive amount of data generated by IoT sensors and devices is a key asset and must be stored, processed, and analyzed to extract value using Big Data analytics. This data is the key for further processing.
6) Interoperability
The diverse hardware and software components in IoT systems must smoothly interoperate through standardized protocols and architectures. This interplay is the key to the overall connectivity between the hard and software components.
7) Agility
Programming tools like Python and Node-RED facilitate rapid IoT application development and enable pivoting based on evolving needs. Consequently, this agility drives innovation, resulting in faster operations.
8) Scalability
It is a well-known fact that IoT solutions are designed to handle hyper-growth in sensors and data volumes. This scalability is of paramount significance since the deployments of IoT devices expand across locations, assets, and processes.
9) Security
Given that IoT devices deal with large amounts of data, robust security measures are given utmost priority. Therefore, encryption, access control, data security, authentication, and other measures are imperative to counter the threat of cyber-attacks.
10) Automation
Automation is the key to enhanced productivity of IoT devices. Insights derived from IoT data analysis can drive automated and predictive control of processes and devices, eliminating tedious human effort. Thanks to the automation of several tasks, efficiency is enhanced, and the time required for the completion of the operation is reduced.
