The “things” in Internet of things, or IoT, refer to the devices, machines, or other objects embedded with sensors that gather, store, and analyze information. When these "things" link to the Internet and a central data server, they can upload that data for further processing, and use it to make many tasks easier to perform.
What makes a thing “smart”?
The ability to send and receive information makes “things “smart, which is possible when something is connected to the Internet. This means, a "thing" doesn’t need to have super storage or a supercomputer inside of it but it just has to connect to super storage or a supercomputer.
Why does it matter?
IoT-equipped devices include smartphones, laptops, and home and personal appliances such as coffee machines, refrigerators, Google Home, Apple watches, and Fitbits. These and many other everyday objects are increasingly becoming smart as they collect and exchange data over the Internet. For example in the Energy industry sensors can be used to monitor lighting, temperature, energy use, and more. By processing that sensor data, intelligent algorithms can micromanage energy use in real-time far more effectively than individuals can, saving money and energy. As well as IoT can be very handy in disaster warning by collecting critical information about the environment, allowing for early detection of environmental disasters, such as earthquakes and tsunamis, thus saving lives.
Some of the IoT applications are,
1. Smart Home
One of the most common applications of IoT technology is in smart homes, where devices such as thermostats, lighting systems, and security systems are connected and controlled through a central hub. This technology allows homeowners to remotely monitor and control their homes, creating a more convenient, energy efficient, and secure living environment.

Smart home assistants: The device which controlled through voice commands, allowing homeowners to control various devices and access information hands-free.
2. Healthcare:
IoT technology is also transforming the healthcare industry, with wearable devices like smartwatches and fitness trackers and as well as remote monitoring tools. Which can track vital signs and send data to healthcare providers, allowing for early detection of health issues and more personalized care. This technology is especially important for patients with chronic conditions, as it allows for more personalized and effective care.
Remote Patient Monitoring: IoT devices collect a continuous stream of real-time health metrics such as heart rate, blood pressure, temperature, and glucose monitoring, etc. This allows patients and doctors to keep track of an individual’s health when not in the doctor’s office resulting improved outcomes and reduced costs.
Ingestible sensors: Collect information from digestive and other systems in a much less invasive way. They provide insights into stomach PH levels or help to figure out the source of internal bleeding.
Connected contact lenses: These smart contact lenses are being formulated to measure glucose levels in the tear and send a warning the levels are elevated.
Robotic Surgery: The surgeon can perform complex procedures by deploying internet-connected miniaturized instruments inside the human body. Advantages include minimally invasive, shorter hospitalization, and speedy recovery.
3. Manufacturing:
IoT technology is being used in manufacturing to improve efficiency and reduce costs by improving supply chain visibility, optimizing production processes, and reducing waste. Connected sensors and machines can monitor equipment performance, detect defects, predict maintenance needs, and optimize production processes in real time, improving overall productivity and reducing downtime.
Improve worker safety — IoT sensors can monitor for safety hazards and security threats in industrial settings, reducing the risk of accidents and unauthorized access.
Predictive maintenance of machinery-IoT sensors can monitor equipment performance and predict when maintenance is needed, reducing downtime and increasing equipment lifespan hence Increasing production.
Enhanced product quality Control— IoT sensors can monitor product quality in real-time, allowing manufacturers to quickly identify and address quality issues and improve customer service by faster product deliveries.
Supply chain optimization: GPS and sensors can track shipments, monitor inventory levels, and optimize logistics operations to reduce costs and improve efficiency.
Improve operational efficiencies — IoT sensors can monitor energy usage in factories and other industrial settings, identifying areas where energy efficiency can be improved.
4. Transportation:
IoT is transforming transportation by making it safer, more efficient, and more sustainable. Connected vehicles can communicate with each other and with traffic management systems, reducing traffic congestion, accidents, and emissions. Additionally, IoT can enable predictive maintenance of vehicles, reducing downtime and maintenance costs.
Fleet Management: IoT sensors can monitor the condition and location of vehicles in real-time, optimizing routes, and maintenance schedules, reducing downtime and improving fuel efficiency.
Public Transportation: These sensors can provide real-time information on public transportation schedules and vehicle locations, enabling commuters to plan their journeys more efficiently.
Smart Traffic Management: IoT sensors can monitor traffic flow and identify congestion hotspots, enabling real-time adjustments to traffic light timings and rerouting of vehicles to improve traffic flow and reduce congestion
Connected Cars: Connected to IoT technologies drivers can access real-time information on traffic conditions, road hazards, and parking availability which helps in improving safety and reducing the time spent looking for parking.
Sustainability: With the support of IoT devices vehicles can monitor emissions and fuel consumption, enabling transportation providers to optimize fuel efficiency and reduce emissions.
5. Agriculture:
IoT technology is transforming agriculture by improving crop yields and reducing waste. Connected sensors and devices can monitor soil moisture, temperature, and other environmental factors, allowing farmers to make more informed decisions about irrigation and crop management. Sensors monitor soil moisture and take weather into account so that smart irrigation systems only water crops when needed, reducing the amount of water used.
Precision Agriculture: IoT sensors can monitor soil moisture, nutrient levels, and temperature, enabling farmers to optimize irrigation and fertilization schedules and reduce water and fertilizer usage.
Livestock Management: Using sensors and other tools farmers can monitor the health and behavior of livestock, enabling farmers to identify early warning signs of disease or distress and provide timely interventions.
Farm Machinery and Equipment Monitoring: IoT sensors can monitor the performance and location of farm machinery and equipment, enabling farmers to optimize maintenance schedules and reduce downtime.
Agricultural Drones: Ground and Aerial drones are used for the assessment of crop health, crop monitoring, planting, crop spraying, and field analysis
Environmental Monitoring: Farmers rely on the satellite weather forecast to have an awareness of weather conditions and other environmental factors, enabling them to make data-driven decisions about planting, harvesting, and other agricultural activities.
6. Retail:
IoT technology is also transforming the retail industry, with connected devices and sensors like beacons allowing retailers to collect data on customer behavior and preferences. This data can be used to personalize marketing efforts and improve the customer experience.
