Understanding IoT (Internet of Things)

The Internet of Things (IoT) is a network of interconnected physical devices, vehicles, buildings, and other objects embedded with sensors, software, and network connectivity. This enables the objects to collect and exchange data, making IoT a critical technology driving digital transformation in various industries, including transportation, healthcare, manufacturing, and agriculture.

How IoT Works

IoT works by connecting devices and systems through a series of steps:

  1.  Data Collection: IoT devices are equipped with sensors and actuators that gather data from their surroundings. This data may include temperature, humidity, light levels, air quality, and other relevant parameters. These sensors can be embedded in smart sensors, wearables, smart appliances, industrial equipment, and other devices.

  1. Data Transmission: The collected data is transmitted using various communication protocols, such as Wi-Fi, Bluetooth, LoRaWAN (Low Range Wide Area Network), or cellular network to a central hub, gateway, or cloud-based platform for further processing and analysis. The communication protocol chosen is determined by criteria such as data transmission distance, power consumption, data volume, and other special requirements of the IoT system.

  1. Data Processing: Upon being received, the data undergoes processing and analysis, either at the edge (that is, on the IoT device itself) or in the cloud, using advanced analytics techniques and machine learning algorithms. Edge computing is the process of processing data locally on an IoT device, which reduces the quantity of data that must be transported to the cloud and enables real-time or near-real-time decision-making. Cloud computing, on the other hand, entails analysing data in remote servers using advanced analytics techniques, machine learning algorithms, and other data processing tools to draw insights, patterns, and trends.

  1. Action: Based on the analysed data, decisions are made and appropriate actions are taken. These actions may include sending commands to actuators, triggering alerts, or updating dashboards and reports . Decisions are made and suitable actions are taken based on the evaluated data. like turning on/off a switch, regulating a thermostat, driving a motor, or triggering an alarm, is one of these actions. Sending alerts or notifications to users, as well as updating dashboards and reports to provide insights to stakeholders, are examples of actions.

  1. Feedback: The system continuously monitors the environment and the outcomes of the actions taken, allowing for ongoing optimization and improvement. If a smart irrigation system senses that soil moisture remains low after watering the plants, it can change the watering schedule or duration to maximise water usage. Feedback from sensors, actuators, users, and other sources can be collected to constantly enhance the performance and efficiency of the IoT system.

Several technologies and precautions can be used in smart cities to ensure data security. A key security method called encryption involves putting data into a coded format that prevents unauthorised access. End-to-end encryption can be used to safeguard data from IoT devices to the central hub or storage during the full communication process. Only

authorised people or devices can access data and systems in smart cities by using access control mechanisms like authentication and authorisation.
