Explore 40 IoT applications for business leaders to select the correct use case for their IoT implementation:

Smart Factories

1. Enterprise asset management

Enterprise asset management involves work management, asset maintenance, planning and scheduling, supply chain management, and environmental, health, and safety (EHS) initiatives.²  Businesses collect real-time data from an asset with IoT sensors.

Businesses are rapidly adopting smart asset management systems into their businesses. Due to their asset-intensive environments, we mostly encounter IoT asset monitoring in industries such as logistics, retail, and manufacturing.

IoT-powered asset management increases real-time visibility of assets and helps businesses optimize their resource while providing benefits such as:

• Increased operational efficiency
• Better control over the sales lifecycle
• More efficient safety and compliance checks
• More responsive smart environment.

2. Predictive maintenance

Maintenance is conducted to prevent predicted problems. So over the lifetime of a machine, some components may never be checked if they are not predicted to cause problems.

For example, A robotics company that is working on reducing the downtime of machines with IoT technology uses sensors to predict when the failure of the component will happen.³

3. Industrial process automation/optimization

Organizations can keep a real-time record of the metrics of all the machines inside a plant using IoT and IP networks. Manufacturers can use this data to automate workflows and optimize production systems. Automation and optimization support industrial companies to reduce costs and increase the quality and volume of output.

The market for automated industrial robots is proliferating. The market size is expected to reach $165 billion in 2028.⁴  

4. Energy management

Energy can be a costly input for industrial businesses. With fluctuating energy costs and strict government requirements for efficiency, managing energy distribution becomes important.

IoT devices can help manufacturers manage energy consumption based on real-time data collected from devices. Intelligent energy management systems reduce energy bills, operational expenditures, and the carbon footprint of the factory while increasing energy efficiency. Some IoT platforms provide IoT applications, including energy management, to optimize the energy consumption of businesses.⁵

Smart Cities

Kay Sharpington from Gartner, states “…Governments across the globe continue to use IoT technologies and solutions to improve citizen safety. At the same time, the falling endpoint and connectivity costs make smart city initiatives more viable”.⁶

With the growing interest in smart cities and the demand on IoT services, the IoT in Smart Cities Market is expected to expand from $230 billion in 2024 to ~$1,5 trillion by 2034. ⁷ Some of the use cases of IoT applications in smart cities are listed below:

5. Outdoor surveillance

IoT-enabled surveillance systems integrated with artificial intelligence and machine vision allow governments to automate monitoring of streets using connected devices such as IoT CCTV cameras.

These IoT systems collect data, process video feeds in real time, and provide actionable insights to law enforcement, enhancing public safety. However, as these devices process personal information, implementing robust data encryption, access control, and oversight mechanisms is critical to minimize risks of misuse while maintaining security.

6. Smart lighting

Additionally, automated systems for electronic toll collection streamline vehicle flow, improving fleet management and creating more efficient road networks.

8. Public transport optimization

IoT solutions in public transport leverage connected devices to provide passengers with real-time updates on schedules, delays, and estimated arrival times. IoT platforms also enhance fleet management by optimizing routes, schedules, and energy usage for buses, trains, and trams. By improving resource management, IoT systems create better commuting experiences and maximize the efficiency of mass transit infrastructure.

9. Smart parking

In cities like San Francisco, parking is a big problem. IoT solutions simplify parking by connecting IoT sensors to parking lots to detect vehicle presence and exchange data with mobile devices. IoT platforms process the data and share real-time updates on vacant spaces with drivers via mobile apps, enabling smoother parking experiences.

By reducing time spent searching for parking, smart parking systems enhance resource management, reduce traffic congestion, and improve overall city infrastructure efficiency.

• The working principle of smart parking is:
• Drivers check mobile apps to identify vacant parking spaces close to the location they aim to go to.
• Sensors are attached to parking lots to detect parked cars
• Measurements are periodically sent to the cloud by microcontrollers
• Mobile Apps use cloud data to identify empty parking spaces,

These connected devices help optimize urban environments and improve quality of life while ensuring compliance with local laws.

11. Structural health monitoring

IoT-enabled predictive maintenance systems facilitate continuous monitoring of buildings, bridges, and other critical structures. IoT devices collect real-time data on vibrations, material wear, and structural conditions, which is analyzed to predict potential failures. By using machine learning algorithms, these systems optimize maintenance schedules, enhance worker safety, and prevent costly structural damage.

12. Waste management

Traditional waste collections are complicated and costly since a fleet of trucks drives along busy streets using inefficient routes. Fill levels of garbage containers differ for each container, ranging from overflowing to partially filled to empty. IoT sensors can monitor fill levels for conventional bins and send the data to the relevant department of the city hall. With that information, the garbage truck routes can be optimized for trash collection.

Machine learning methods can also be implemented in IoT sensors (i.e. edge analytics) so that sensors can predict the fill levels of containers by learning from historical data.
