• An IoT-backed security solution uses real-time data to provide mitigation tactics and prevent cybersecurity attacks. It can even prepare incident responses and security policies based on network activity. 
• Another obvious application of the Internet of Things is decision-making based on customer analytics. Never before have enterprises had so much real-time data to work with.
• Information technology infrastructure library (ITIL) refers to detailed practices for IT asset and service management. These practices focus on aligning IT services with business requirements. Enterprise infrastructure is more complex now than ever–various devices communicate with each other to make the system work. ITIL practices need to be strategically considered while creating the ITIL, with IoT eventually feeding the library itself.

2. Integrating smarter homes

The most visible application of the Internet of Things is a smart home. A smart home uses sensors to control and maintain lighting, resource management, and security systems. A smart home is a smaller, independent version of a smart city. 

An example of an IoT-based smart home system is Mark Zuckerberg’s Jarvis. Zuckerberg’s smart home system uses natural language processing for the contextual processing of voice commands. He has internet switches to operate the appliances plugged into them. The system takes care of lighting rooms based on occupancy and even playing personalized music based on who is in the room. His security system uses facial recognition to alert the family of the identity of their visitors. 

3. Innovating agriculture

Agriculture, as an industry, could massively benefit from the Internet of Things. The world’s human population is estimated to grow to around 10 billion by 2050. As such, governments are prioritizing the scaling up of agricultural systems. This, combined with climate change, has farmers marrying technology to cultivation.

• Sensors are used to provide details of soil chemistry and fertilizer profiles. CO2 levels, moisture, temperature, level of acidity, and the presence of appropriate nutrients all contribute to how good a harvest turns out to be. 
• Smart irrigation is an IoT application to regulate and efficiently use water for farming. The IoT system only initiates the water flow when the soil reaches a certain dryness level. It also stops the supply once a certain level of moisture is reached. This reduces wastage caused by human errors.
• Livestock tracking involves the use of RFID chips to keep track of an animal’s vitals, vaccination details, and location. 
• A smart greenhouse uses microclimate to raise crops instead of relying on changing weather patterns. Sensors monitor and control all parameters and have automated systems for light and water. 
• Predication farming is the practice of using information collected over time to hone and implement agricultural practices. The data provided by these sensors allow farmers to decide on the ideal growth parameters and suitable fertilizers. 

Cainthus, a Dublin-based vision company, uses predictive imaging to monitor livestock. It tracks key data such as food and water intake, behavior patterns, and heat detection. Farmers can use this information to decide milk output, reproduction management, and overall animal health. It even boasts proprietary software to recognize animals based on hide patterns and facial recognition. 

4. Building smarter cities

A smart city is an urban city that uses sensors and cellular or wireless technology placed in ubiquitous places such as lamp posts and antennae. There are multiple facets in which one can incorporate IoT into the functioning of a city:

• Traffic management: Sensors on roads and traffic signals send data to the IoT systems. This data, accumulated over time, allows officials to analyze traffic patterns and peak hours. It also helps create solutions for bottlenecks.
  Commuters can use this information to determine which areas are congested and what alternate routes can be used. A version of this already exists in third-party map services such as Google Maps.

• Pollution monitoring: A pressing problem faced by every country in the world is air pollution. With existing sensors, one can easily measure parameters such as temperature, CO2 levels, smoke, and humidity. Smart cities leverage this to gather data about air quality and develop mitigation methods.
• Resource management: The biggest factors in deciding a city’s livability are waste, water, and electricity management.
  With water management, sensors are attached internally or externally to water meters. These sensors provide information to understand consumption patterns. They detect faults in supply and automatically begin the necessary course of action. Trends in water wastage can be used to develop an efficient water recycling system.
  IoT-enabled waste management systems produce a geographical mapping of waste production. These systems trigger the clearance process themselves; for example, by generating alerts when a trash bin is full. They also provide more insights into waste segregation and how people can improve waste processing.
  Electricity management comes in the form of a smart grid, covered in detail in this article.
• Parking solutions: Parking woes, while sounding insignificant, play a big part in traffic management. Smart parking solutions provide drivers with real-time information about empty spaces available. 
• Infrastructure management: Public infrastructure such as street lamps, roads, parks, and gas supply lines cost a lot to maintain. Repair work in any of these causes disruptions to everyday functioning. IoT-based maintenance and monitoring systems lookout for signs of wear and tear while analyzing patterns. This proactive approach can save a city a lot of money.
• Disaster management: The Internet of Things can be used to hook up disaster-prone areas to a notification system. A forest fire, for example, can be detected and curbed before it grows beyond control. 

In 2017, Spain announced that it was turning its Balearic islands into an IoT lab. Sensors have been deployed on existing TV and radio masts to track air and noise pollution levels. Officials also plan to use IoT for tourism and crowd management.

In Palo Alto, California, a smart parking system has been implemented across parking spots in the city. It guides drivers to the nearest parking spot and has proven to reduce traffic congestion.

5. Upgrading supply chain management

Supply chain management (SCM) is a process that streamlines the flow of goods and services from raw material procurement to the customers. It involved inventory management, fleet management, vendor relationships, and scheduled maintenance. 

During the pandemic, many businesses were affected by supply chain issues, especially when it caused a global shutdown in early 2020. As operations switched to being remote, it made sense for organizations to consider integrating IoT into their SCM processes.

The most prominent example of wearable IoT technology is the Fitbit. The Fitbit tracks user activity and sleep patterns to encourage a healthy lifestyle. 

9. Integrating connected factories

The Internet of Things is all about giving physical devices more digital prominence. What better application for this than on a factory floor?

Industrial IoT (IIoT) is the Internet of Things at a factory level. IIoT is often referred to as the fourth wave of the industrial revolution or Industry 4.0.

• Most factories subscribe to enterprise asset management (EAM) and computerized maintenance management systems (CMMS) for maintenance management. Combining these with IoT-enabled sensors extends the physical life of machines and ensures availability and reliability.
• Real-time monitoring of devices ensures predictive care and optimal machine health. Condition-based maintenance (CBM) is a maintenance strategy that monitors asset health and performs maintenance only if necessary. IoT enables this and cuts costs.
• IIoT goes beyond supply chain management and maintenance management. Aggregated data assists in the optimization of product development and quality testing. It can improve everything from packaging to management. IIoT can automate many manual maintenance functions, which, in turn, automates mass production.

Volkswagen has decided to turn its main plant in Wolfsburg, Germany, into a smart factory. It has enlisted Nokia to create an IoT system centered on a standalone 5G network. It is currently testing smart factory use cases to fine-tune and discover new capabilities.

10. Reshaping hospitality

The hospitality industry has had several upheavals due to the unprecedented pandemic. The cost of staff and upkeep did not keep up with the travel restrictions placed across the world. 

• One way to offset costs is to turn to the Internet of Things for automation. Interactions can be kept to a minimum, in line with social distancing norms that seem to come and go. Mobile electronic keys, for example, eliminate the need to personally check into a hotel. 
• Using electronic keys keeps hotel management informed of a guest’s location within the hotel. Extra requests can also be directly charged on the fly.
• Room service and housekeeping requests can be made through a mobile phone.
• Smart lighting and appliances make for a good customer experience. 

The YOTEL hotel in Singapore boasts of all these IoT systems. They also have adjustable smart beds, adjustable lighting, and smart TVs. The hotel even has robots to perform basic housekeeping tasks. 

IoT trends such as self-driving cars have not been included here. While they have been in play for a while, there is a lot more work left to make it a seamless reality. Self-driving cars and countless other applications are those that the world looks forward to in the near future.
