On the other hand, the business of industrial IoT (IIoT) focuses on improving operational efficiency, reducing costs, and improving customer experiences.

For example, you can use IoT to monitor equipment performance in manufacturing, predict maintenance needs, and optimise production processes.

Your IoT sensors optimise irrigation needs and processes, track livestock’s health, etc., in agriculture.

1.3. How IoT Works- Role of Smart Devices, Connected Devices, and Machine-to-Machine Communication (M2M)

IoT devices are our eyes and ears when we are not present physically where they are installed.

IoT technology works in 3 steps. Here is the workflow for the 3 steps of IoT devices, so you can understand the process easily.

Data Capturing: Devices embedded with sensors capture data from their surroundings. This could be simple temperature capturing or complex real-time video.
Data Sharing: After capturing the data, the devices share the data over a network connection to other connected devices. This happens through machine-to-machine (M2M) communication, where no human interaction exists. The devices can send the data to the private or public cloud system, to another device, or store the data in local storage as directed.
Data Processing: When the devices send data to other devices, the software that is programmed to do something processes the data. This may be turning on a light, sending a warning to someone, or showing the temperature of the surroundings.

In an additional step called “Act on data,” the system analyses the data, and you will get insight into the data, which helps you to make informed business decisions.

2. Key Technologies Driving IoT Integration

To power up the IoT technology, the following technologies play the leading roles behind the scenes.

2.1. Sensors and Actuators

Sensors are devices that detect changes in the environment (e.g., temperature, motion, humidity, pressure, light, etc).

Multiple sensors make sensor networks, and they work together to monitor environments, which is essential for sectors like agriculture and manufacturing.

On the other hand, actuators are the devices that perform the actions you programmed for(e.g., opening a valve, switching on a light, etc.).

Both sensors and the actuators enable automated responses in IoT systems.

2.2. Edge and Cloud Computing

Edge computing is a distributed computer framework. This framework brings the processing capabilities near the source of data in IoT devices instead of a centralised data processing system. This reduces latency and bandwidth usage.

Edge computing, such as autonomous vehicles or industrial automation, is crucial for real-time responses.

Cloud computing offers you scalable storage and processing power in an IoT system. This enables businesses to handle a vast amount of IoT data efficiently. IoT Cloud Platforms provide tools and services to manage devices, analyse data, and integrate with other systems.

Hybrid models combine both edge and cloud computing, allowing your IoT system to process immediate data at the edge and store and analyse long-term data in the cloud.

2.3. Data and Connectivity

Big data analytics processes vast datasets from IoT devices. This uncovers patterns and insight that inform you about business strategies.

Wireless Communication Standards

IoT technology primarily uses wireless communication connectivity.

Bluetooth Low Energy (BLE): BLE is also known as Bluetooth Smart. It is a wireless technology, Ideal for short-range, low-power applications like wearable devices.
