IoT or Internet of Things is a trending technology that has applications in many sectors, from security to farming. IoT can be defined as a network of devices that are interconnected with each other. The number of devices in an IoT network can be anywhere between 2 or 3 to hundreds. Sensor technology and automation are very important functions in IoT. In this blog, we will look into 20 real world Internet of Things examples.

Application 1: Connected Car

You would have read about cars that run by themselves in sci-fi books or watched them in movies. AI and IoT have made that dream a reality. Now, there are cars that can run by themselves. The self-run cars can work on voice commands transferred over a connected smartphone. They can also predict machine failure in the early stages or even before they happen. A smart car is capable of analysing obstacles and blocks and preventing accidents, but scientists are still not sure if smart cars can handle the traffic conditions on the road. Right now, connected cars are suitable for controlled environments.

Application 2: Smart Home

While talking about IoT applications, Smart Home is one of the first things that everyone talks about. A smart home IoT connects appliances used at homes such as washing machine, coffee maker, microwave oven, security system, air conditioner, and refrigerator, and even the lighting system and the door. You can control all the devices from your smartphone or computer system. The appliances can also be automated to start and stop at specific times. When you are going back home in the evening, you can activate the lights at home just as you get near to your house. You can also check if the door is locked or if the dishwasher is turned off right from the connected device. IoT Smart homes can help you save on electricity.

Application 3: Smart City

Smart City is a dream that can be made real with the help of IoT and artificial intelligence. This network can include water management, street lighting, electricity management, traffic management, waste management and more. By integrating sensors in buildings, we can detect wind pressure, seismic activities, and other natural factors to predetermine natural calamities.

Application 4: Precision Farming

Another of IoT’s applications is in precision farming. Data science tools can be used to collect and analyse data such as humidity, soil pH, weather conditions, rainwater availability, and lots more. The nutrients in the soil and its pH can be analysed to determine which plants will grow best. IoT can be used to remotely activate the water pump or turn it off while irrigating the fields. It can also be used to control the flow of water in drip irrigation. There are numerous other ways in which technology can be used to improve agricultural practises and enhance yields.

Application 5: Agricultural Drone

A drone can be used to survey large stretches of land to see if there are any problems such as rodent and pest attacks, evaluate the health of the crop and check if there is any water stagnation in the fields. Drones can also be used to spray fertilizers and weedicides in the field.

Application 6: Smart Grid

A Smart Electric Grid can be used to optimize electricity usage based on customer requirements. When the load is heavy, it can give recommendations to customers to reduce usage. In the case of electric failure, the electric grid can be programmed to reroute electricity.

Application 7: Connected Factories

A connected factory can be built using IoT. This technology can take over the job of a supervisor and still do more. The factory can be run round the clock with minimal human intervention as most of the tasks and transport are automated. The labourers can be asked to work on safe tasks while dangerous tasks can be handled by machines.

Application 8: Smart Retail

IoT can make shopping a more enjoyable experience for customers. There are many ways in which AI and ML can be applied in large retail outlets. Automated checkout counters reduce the need for long queues and allow customers to self-checkout their purchased items. The bill can be paid via digital payments. Sensors can be placed on the shelves, which will send notifications when the products are out of stock or if the stock has reduced. Automated inventory management makes it easy to manage product availability in the store.

Application 9: Supply Chain Management by IoT

Supply chain management is a complex process that involves many steps and human intervention in many areas. IoT can help streamline the supply chain management process, right from the procurement step to the delivery stage. Shipment tracking, inventory management, scheduling of product arrival and departure, and other processes involved in supply chain management can be automated and connected to ensure a seamless experience.

Application 10: Traffic Monitoring System by IoT

IoT can also be effectively used for traffic monitoring with minimal human intervention. The traffic signals across different roads can be connected and designed to change based on a specific algorithm. It will need human intervention only in cases when there is an ambulance movement or any other emergency. Surveillance cameras can be set up beside traffic signals or other parts of the road to monitor traffic. The videos captured can be studied to check for traffic violators or any other purpose.

Application 11: Forest Fire Detection by IoT

Remember the recent Amazon fire and that huge fire in Australia that destroyed millions of acres of forest cover, wildlife and even human life and property? In most cases, forest fires can be stopped if detected early. Different kinds of sensors such as temperature sensor, humidity sensor, soil moisture sensor, accelerometer sensor, ultrasonic sensor and others can be setup to track and identify minute changes in the environment. The data gathered by the sensors can be analysed to see if there are any indications for a forest fire. If so, precautions can be taken to prevent this natural calamity.

Application 12: Portable Water Quality Assurance

A survey shows that if the current rate of environmental pollution continues, then nearly one-third of the world population will not have access to good portable water. Sensors can be used to detect salinity, pH, turbidity, oxidation-reduction rate, and other parameters to determine the quality of water. The sensors can also be used to detect arsenic or lead poisoning at the early stages. IoT can be used to determine the quality of water in reservoirs to ensure that all residents get good quality water.

Application 13: Structural Health Monitoring

Structural health monitoring through IoT helps check the stability of construction at periodic intervals. Sensors can help collect data related to structure strain, vibrations, crack widths, moisture, and lots more. The data can be analysed to evaluate the remaining life of the structure.

Application 14: Radioactivity Monitoring

Nuclear power plants generate huge volumes of power. The downside is that there is always a chance for radioactive leaks, which can lead to very dangerous consequences. IoT applications can be used to continually monitor radioactive levels in the nuclear reactor and the surrounding regions. GM counters can be used to gauge the radioactive levels and send the data to the Cloud. A Node MCU and GPS can be used to detect the location from where the data was sent. All this information can be collated to identify risks at an early stage.

Application 15: IoT Controlled Golf Course

All IoT application examples are not just for environmental protection and individual safety. There are a few applications that are also used in sports, for example golf. There are many factors such as humidity, soil moisture levels, rainfall, and other conditions that determine the gameplay. Using sensors, all these factors can be monitored and updates sent to a connected device. The golf course can be neatly maintained based on this information. At the same time, this data can be shared with golfers, which will help them plan their game.

Application 16: IoT in Packaging Industry

Market studies determine that the packaging industry is set to grow by nearly 18% in the next year. This growth can be attributed to the fast development of the e-commerce sector and online shopping. As more products are being delivered to the doorstep, the demand for packages is also in the increase. IoT solutions can be used to automate certain processes in packaging manufacturing, which can reduce time, money, and human intervention. Digital labels can be affixed to packages to make tracking easy and efficient.

Application 17: Landslide Detection by IoT Application

Landslides are natural calamities that happen because of both human activity and natural phenomena. Landslides lead to loss of lives and property. Sensors can help determine soil moisture levels and soil movement, and send notifications with location details. The data can be analysed to predict possible landslides in a location. Preventive and precautionary action can be taken to prevent landslides, if possible or at least life and property.

Application 18: The Volume of Visitors Check by Smart Phone Detection

This application comes handy while monitoring large events where there is no limit to the number of visitors. IoT sensors can be placed at the entry, exit, and public transportation areas. The sensors collate data regarding the number of people and maximum people movement areas. This data can be analysed to calculate visitor’s volumes, average stay time, and people behaviour. The information can be used while planning other such events.

Application 19: Waste Management IoT Application

Waste management is a critical problem that governments all over the world are facing. There is so much waste being generated almost every day that managing it is a humungous task. IoT waste management involves setting up sensors on each bin placed in different locations across the city. When the waste is filled to a threshold level, a notification is sent to the connected device via Cloud. Based on the analysis of the notifications, the administrator can prepare a schedule for removing the waste from the bins.

Application 20: Urban Noise Detection

Noise pollution can be controlled by using IoT applications. Sensors can be used to detect noise levels in different parts of the city, and more so near hospitals, schools, and other regions. If the noise levels are higher than mandatory levels, then the requisite steps can be taken to reduce the noise.


IoT is bringing about a huge change in different sectors across verticals and horizontals. By properly using this emerging technology, we can change the shape of the future. Many leading companies have realised the importance of IoT and are investing in research and development in this field. The Internet of Things is a technology that is here to stay.
