What is the Difference Between IoT and AI

Now that you are brushed on how AI and IoT are different from each other, let's have a closer look.

1. Difference Between IoT and AI: Purpose

Though AI can be implemented alongside IoT, the purposes of both systems are distinct. 

• IoT: IoT functions like a network that lets users connect and interact with objects from any global location. It is the interconnectedness of physical objects that can communicate with one another without the need for human intervention, such as sensors, actuators, and other essential electronics. The goal is to enable items to transmit and receive data via the Internet. For example, temperature sensors are the most commonly used IoTs. They record temperature variations and identify heat. Additionally, motion sensors use ultrasonic wave monitoring to identify movement and initiate an action that is wanted when those waves are disrupted. 
• AI: Artificial Intelligence (AI) aims to imitate human intelligence and behavior in machines, hence promoting more compassionate behavior. The aim is to develop technology that facilitates human-machine collaboration. For instance, people frequently receive personalized recommendations from artificial intelligence based on past searches, purchases, and other online activities.

2. Difference Between IoT and AI: Dependability

Dependability relates to human intervention, and IoT and AI have distinct dependability rates. 

• IoT: IoT enables data to move between different physically connected devices, and AI aids in data interpretation. Through a vast network of linked devices, the Internet of Things (IoT) generates a vast amount of data, much of which is not even captured and some of which loses value in milliseconds. This necessitates a method for deriving insights from the data via intelligent analysis. As a result, IoT has higher dependability compared to AI systems.
• AI: Compared to IoT, AI systems depend on humans, especially during the development and training phases. They may also require intervention to address adversarial attacks, model drift, and unintended consequences, which may be somewhat predictable.

3. Difference Between IoT and AI: Scalability

Regarding scalability, IoT takes the front seat for many reasons. 

• IoT: The current cloud-based framework makes it easier to grow IoT initiatives. Numerous variables, such as pace and architectural design, might impact a project's scalability. However, scaling any IoT project developed with scalability in mind is simpler.
• AI: The large number of variables makes scaling AI projects somewhat challenging. However, additional flexibility and modularity in the architecture facilitate more straightforward scalability. Inadequate data quantity can restrict the system's resilience and generalization, while poor data quality can result in erroneous, biased, or untrustworthy AI outputs.

4. Difference Between IoT and AI: Costs

The cost of AI systems lies on the higher end than that of IoT as it involves multiple, high configuration requirements to function. 

• IoT: IoT projects often involve expenses for host servers (if applicable), hardware, wireless connectivity, and corresponding software development. The cost of IoT is lower than that of AI. The expense of purchasing specialized controllers is additionally decreased by the ability to control IoT devices using portable electronics like smartphones.
• AI: In contrast, data collection, software development, model deployment, data lakes/warehouses, and model deployment are typically associated with expenditures associated with AI projects. Highly configurable system architectures are needed for AI to execute massive computations. Therefore, renting or leasing distant servers comes at a slightly higher cost.

5. Difference Between IoT and AI: Success Rates

Artificial intelligence projects often have a lower success rate than the Internet of Things.

• IoT: Businesses can achieve success by having a thorough understanding of consumer behavior and decisions. With the Internet of Things, this is now feasible. Businesses can use IoT to collect, track, and analyze data from mobile, social media, video surveillance, and internet usage. IoT has simple and workable systems, making its success rates slightly higher than AI's.
• AI: Compared to IoT, AI projects often have a lower success rate. According to an IDC poll, only 30% of the organizations claimed the highest success rates for AI. The failure rate for the remaining cases varied from 10% to 49%. Among many others, one of the leading causes of AI project failures is a need for more data (both high-quality and high-quantity).

6. Difference Between IoT and AI: Data Requirements

Data is the basis of AI, while IoT requires hardware systems, sensors, and minimum data to function. If you want to dive into the details of data requirements and management under each system, you can take up the best Data Science courses.

• IoT: The foundation of the Internet of Things is the collection of moments from sensors, which collect, store, and retrieve data upon demand. Therefore, the more sensors used, the more influential the data collection.
• AI: Artificial intelligence possesses the ability to comprehend patterns and actions. Massive amounts of data, including patterns, trends, and knowledge of human behavior, are needed for AI. To carry out tasks like data modeling and many more, the data utilized in AI must be preprocessed and relevant.

IoT and AI: Which One Should You Choose?

There’s no one answer to “IoT vs AI, which is better.” AI and IoT both have significant and promising prospects. Both individually and as a group. 

Companies often use IoT because of its capability to accumulate real-time information when the primary goal is to collect real-time data from multiple devices or environments. Moreover, IoT is a preferred tool where continuous, remote monitoring of physical assets is required. 

On the other hand, when companies already have enough data sources and want to jump into extracting insights and making predictions, they often benefit more from utilizing AI than IoT. AI can analyze historical data and generate actionable insights without additional IoT sensors.

Thus, the choice between IoT and AI solely depends on what kind of problem you want to solve. Whether it concerns data generation and interpretation or human errors and low productivity. 

However, nowadays, AIoT is the talk of the town. AIoT, short for Artificial Intelligence of Things, is a transformative concept that combines two. AIoT leverages the capabilities of AI to enhance the functionality and intelligence of IoT devices and networks. It allows these devices to gather, analyze, and act upon data in a more advanced and autonomous manner. 

Final Thoughts 

Artificial Intelligence and the Internet of Things are two separate but complementary ideas. AI systems can analyze, learn from, and automate tasks using data from IoT devices. They are concerned with analysis, interpretation, and decision-making, whereas IoT is more concerned with connectivity and automation.

There are several distinctions and parallels between how IoT and AI operate. However, both have a significant impact, provided their potential is correctly utilized in the business process.
