Internet of Things (IoT) applications are becoming more widespread. According to Mckinsey, the percentage of businesses that IoT technology has increased from 13% to 25% between 2014 and 2019.
IoT enables a myriad of different business applications. Knowing those applications can help businesses integrate IoT technologies into their future investment decisions. That is why we set out to create the most comprehensive library of IoT use cases.
The image below shows the potential impact of IoT technologies in various industries in 2025.
Smart Factories: Enterprise Asset management
Enterprise asset management involves: work management, asset maintenance, planning and scheduling, supply chain management and environmental, health and safety (EHS) initiatives. Businesses collect real-time data from asset with IoT sensors.
Businesses are rapidly adopting smart asset management systems into their businesses. Due to their asset-intensive environments, we mostly encounter with 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.
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, Fanuc is a robotics company that is working on reducing the downtime of machines with IoT technology. Fanuc uses sensors to predict when the failure of the component will happen.
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 to 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 was 41 billion U.S. dollars in 2017 and is expected to reach 73 billion U.S. dollars in 2023.
Energy can be a costly input for industrial businesses. With fluctuating energy costs and strict government requirements of 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 carbon footprint of the factory while increasing energy efficiency. WebNMS is an IoT platform that provides IoT applications including energy management to optimize the energy consumption of businesses.
According to the 2018 Gartner IoT hype cycle report, smart lighting is the fourth-most mature IoT tech application. Smart lighting aims to optimize energy management.
Smart lighting is made up of street lighting with IoT sensors. Sensors collect data about the condition of traffic and pedestrians. With that data, street lights provide optimum lighting so that street lighting systems can save up to 80% of the energy.
Smart lighting can also be applied to factories or homes.
In cities like San Francisco, parking is a big problem. With IoT sensors, parking problems in a city can be minimized.
Working principle of smart parking is:
- 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,
- Drivers check mobile apps to identify vacant parking spaces close to the location they aim to go to.
In smart cities, sound monitoring systems can monitor noise levels and warn companies that violate limits and help manage noise levels.
Structural Health Monitoring
IoT allows remote collection of architectural data to monitor events such as vibrations and changes in material conditions, predict structural damage, and prepare action plans for structures such as bridges, buildings, stadiums, ships, airplanes, etc.
Traditional waste collections are complicated and costly since a fleet of trucks drive along busy streets using inefficient routes. Fill levels of garbage containers differ for each container: ranging from overflowing, partially filled and 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.
Due to the drastic increase in urbanization levels and importance of water quality in human health, water management is a key topic for cities. A water management system is based on real-time data collected from sensors. Water management can provide the following applications:
Sensors detect the water level in tanks and alerts when the water level is lower than the threshold. Well™, a smart home water conservation system developed by Mindtribe, uses IoT sensors to monitor water usage.
IoT sensors determine the weather condition and the soil moisture, which will help in getting the appropriate amount of water that soil needs. Bosch offers an IoT solution that measures how much water the tree needs and provides that amount of water.
IoT sensors can detect temperature changes, water leakage, chemical leakage, and pressure level in water tanks.
Water Quality Management
IoT sensors determine what kind of chemicals are in the water. They also identify metrics such as total dissolved solids (TDS), bacteria, chlorine, electrical conductivity, etc.
Ultraviolet Radiation Monitoring
Sunlight consists of three major components:
- Visible light: Wavelengths between 0.4 and 0.8 micrometers,
- Ultraviolet light: Wavelengths shorter than 0.4 micrometers,
- Infrared light: Wavelengths longer than 0.8 micrometers.
Ultraviolet (UV) rays are electromagnetic waves that account for about 10% of solar light. When overexposed, UV rays have harmful effects such as skin cancer, premature aging, cataracts, and immune system suppression. IoT sensors measure UV sun rays to warn people not to be exposed in certain hours.
Falling into the ground and not being able to get up or request help can be a scary experience for senior citizens. IoT sensors can detect falls using geo location data and summon help so that it reduces the time the elderly remain on the floor after a fall which could lead to lethal consequences.
Medical fridges monitor the temperature of vaccines, medicines and organic elements for clinics and health centers. Medical fridges provide an opportunity to follow all safety standards and national regulations of the pharmaceutical market using IoT sensors. They prevent medicines and vaccines from spoiling.
Efento is an IoT sensor vendor that has a variety of temperature measurement products along with wireless monitoring of temperature in medical refrigerators.
Patient Surveillance/Remote Patient Monitoring
20% of patients who had surgery are readmitted to the hospital within just 30 days. Remote patient monitoring (RPM) systems use wearables to monitor the condition of patients who are resting at home after surgery. RPM enables real-time data collection about patients’ body temperature which is the main indicator of infections. With RPM, doctors can observe patients’ data and provide early diagnoses without requiring patients to be physically present at the hospital.
Telit is an IoT solution vendor and offers its customers a RPM solution that enhances patient monitoring capabilities and patient satisfaction. Telit’s offering can reduce:
