The Internet of Things is a network of interconnected technological gadgets that exchange information. IoT’s primary objective is to enable remote access and operation of devices with minimal or no human intervention. Internet-connected IoT-enabled devices are meant to exchange information and perform remote activities through exchanging data. These networked electronics and electronic equipment are frequently referred to as “things.” The majority of electrical devices contain inbuilt sensors. These sensors are used to emit data and provide device status information. IoT provides a centralized location for all devices to upload their data and a standard language for them to speak with one another. This data is then examined, and useful information is taken from it based on the requirements and preferences. The outcome is shared among all linked devices. Bluetooth or ethernet can be used to connect devices. Kevin Ashton first invented the term Internet of Things in 1999.
Examples of IoT in Real Life
1. Home Automation
Home automation is a prime example of the Internet of Things. Smart homes or Internet of Things-based home automation systems are growing in popularity. In a smart home, consumer electronic devices such as lights, fans, and air conditioners can be linked via the internet. This connectivity allows the user to control these devices remotely. A smart home is capable of remote access, lighting control, energy management, and expansion. Currently, this IoT application is not widely used because the installation cost is prohibitively expensive, making it difficult for the majority of people to afford it. However, the future of home automation is quite promising.
2. Wearable Health Monitors
Wearable health monitoring is both intriguing and practical. They include intelligent clothing, intelligent wristwear, and medical wearables that provide us with high-quality health services. They are designed to monitor activities such as heart rate, step count, and pulse rate. This information is recorded and can be sent to doctors for a comprehensive fitness evaluation. These IoT-based smart wearable devices have a significant impact on our way of life. In the event of a medical emergency, such as an asthma attack, seizure, etc., they are also capable of raising an alarm and sending an alert.
3. Disaster Management
The Internet of Things facilitates the forecast and management of natural disasters. As an illustration, consider forest fires. To prevent the confusion and destruction caused by forest fires, sensors can be set at the forest’s perimeter. These sensors continuously measure the local temperature and carbon concentration. Regularly, a detailed report is provided to a central monitoring hub. In the event of a forest fire, the control room, police station, and fire department are notified. Therefore, IoT facilitates preparedness and rapid response in the event of an emergency.
4. Biometric Security Systems
Numerous security organizations utilize biometric systems to record daily attendance, restrict access to authorized staff, and provide other services. The Internet of Things is applied in this industry due to its advanced security, data connectivity, and minimal human intervention. In biometric technology, fingerprint, voice, eye, and face recognition are utilized. IoT-based security technologies are more reliable than manual or automated approaches. The devices used in biometric security systems are interconnected and have the ability to transmit data to the host computer after each use. This data is archived for future use, and relevant information is accessed as needed.
5. Smart Cars
IoT can be used to connect vehicles so they can transmit data such as location, speed, and dynamics. According to an estimate, there will be 24 billion linked cars in the world by 2020. We utilize IoT without even being aware of its existence. For instance, when determining the shortest route, driving semi-autonomous smart cars, etc. IoT is being utilized in automobile maintenance and repair. It not only reminds the customer of the scheduled maintenance date but also provides correct recommendations for repairs and maintenance.
6. Process Automation
Manually completing repetitive activities in the manufacturing industry, such as label wrapping, packaging, etc., is tedious and prone to human mistakes; consequently, automation is utilized. For instance, consider the industry of producing cold beverages. In this instance, it is necessary for manufacturing machines and conveyor belts to be interconnected in order to transmit information, status, and data. This link is dependent on IoT. Periodically, the status of the made product and the machine health report is provided to the manufacturer so that errors can be identified in advance. An IoT-enabled industry is advantageous since it increases production speed and preserves product quality throughout manufacturing. It also contributes to a more efficient and secure workplace by decreasing human error.
As a result of climate change and the water issue, farmers face numerous difficulties, such as crop flattening, soil erosion, and drought. Using an IoT-based farming system, it is simple to eliminate these issues. For instance, the IoT-based irrigation system employs a variety of sensors to monitor the soil’s moisture content. If the moisture level falls below a certain threshold, the irrigation pump is automatically activated. In addition, IoT assists farmers in assessing soil health. Before planting a fresh crop, a farmer must restore the soil’s nutrient content. The IoT-enhanced software enables the user or farmer to choose the most nutrient-restorative crops. It also aids in detecting the need for fertilizer and various other agricultural requirements.
8. Shopping Malls
The Internet of Things is most prevalent in shopping malls. In the majority of shopping malls, barcode scanners are utilized to scan the barcodes on all products. After scanning, it pulls pertinent data and transmits it to the host computer. After proper processing, the computer is linked to a billing machine that delivers the bill to the customer. Through the Internet of Things, all of these gadgets are interconnected.
