IoT devices are physical objects that are connected to the internet and have the ability to collect and exchange data. What Is the Internet of Things (IoT) These devices are often embedded with sensors, software, and network connectivity, which allow them to interact with other devices and share data. The data that IoT devices collect can be used to automate and optimize processes, track and monitor environmental conditions, and provide real-time insights into operations. IoT devices allow us to take internet connectivity wherever we go. There are thousands of IoT devices to create seamless experiences where we work and play in enterprise, industrial, and medical applications. If you’re new to the Internet of Things, this article will tell you everything you need to know about IoT devices. What are they? How do they work? And how can you take advantage of IoT devices? Let’s dive in.
What are IoT devices?
There are many people alive today who remember the world before the internet. With the help of the Internet of Things, we are taking connectivity and computation closer to the edge than eversion devices are pieces of hardware that have been programmed to send data over the internet and networks. IoT devices come in many shapes, sizes, designs, and uses. Sensors, actuators, gadgets, appliances, and computational machines all fall under the umbrella of the IoT. Where PCs and other installations are not portable, IoT devices are small digital machines users can take virtually anywhere. They help people collect and make sense of data gathered from the environment with the help of machine learning AI. Some popular IoT devices include home security devices like Ring Cameras, smart home devices like Amazon Alexa or Google Nest, and even smartwatches. IoT devices are designed for an array of applications. They allow people to live active lives with the help of medical devices and implants, help avoid disruptions and bottlenecks for business operations with sensors and predictive analytics, and even allow you to change your home’s temperature from a remote location.
How do IoT devices work?
A technical understanding of the ins and outs of the Internet of Things is optional to know how IoT devices can simplify the lives and activities of humans. An IoT device is a mini-computer that sends information to the cloud. The cloud then processes the information and decides what to do with it. For example, the cloud software may send an alert, adjust a sensor, or display a notification. Most IoT devices are made to work with data without any input from a person other than programming. However, there is a user interface with varying degrees of functionality. For example, some tasks may require users to give the “okay” to perform actions, while others can be tasks automatically. The user’s adjustments through the user interface are sent back through the IoT system, telling the device what to do next. That could be ignoring the alert, recording an anomaly, or sending a message to personnel. Let’s look at how an IoT system functions to understand better how IoT devices work. An integrated IoT system is made up of four parts that allow IoT devices to do what they were programmed to do:
- Sensors or devices
- Connectivity
- Data processing
- User interface
Let’s explore each component in detail.
Devices and sensors
IoT devices and sensors start by collecting data from the environment. This can mean gauging temperature or barometric pressure, learning information from a video lecture, or keeping track of specific operations.
There are many ways that IoT devices collect this kind of information and data from their surroundings. For example, cameras, accelerometers, and GPS are ways machines can collect data to analyze and process. A smart home device listens to your voice, a motion sensor detects vibration patterns in heavy machinery, and a biological sensor is a device that can record several bodily functions such as heart rate, acidity, and other chemical data.
Connectivity
Once an IoT device has collected data from the environment via sensors, it sends that information to the cloud to be processed. How that data gets to the cloud is through connectivity. There are several methods for connecting IoT devices to the cloud, such as WiFi, Bluetooth, satellite, cellular, and 5G. How a device connects to the cloud depends on its specific IoT application, the information collected, and how that information will be used. A device without network connectivity can’t operate as an IoT device. Put another way, data collected on IoT devices are only useful if they can be processed to the cloud. Connectivity is an essential feature of the Internet of Things.
Data processing
When the data collected from a connected IoT device arrives in the cloud, it’s time to process it. Computers still need to communicate qualitative information better and follow strict rules to read, process, analyze, and act on what is put into them. Data processing is where the cloud converts raw data into a machine-readable form so the IoT device knows what should happen next.
IoT devices are programmed to sense and understand certain datasets to perform specific functions and tasks based on that information. Data processing is how the cloud reads and makes sense of data. Sometimes this is a simple process, like ensuring the temperature is adequate, or it could be more complex, like using computer vision to identify safety hazards.
User interface
Without a way to use the data, what good is it? That’s why most IoT devices have some user interface (UI) where people can interact with the device. After the data is processed, the UI generates and offers output to the user. There are many ways that an IoT device can deliver a result. For example, a business owner can receive a text alert when a motion is detected at their location after hours. If the temperature in a cold storage unit is too high, an IoT device can show an alert or automatically start a pre-programmed protocol if the conditions for action have been met. The user interface is how users can communicate with the IoT device and tell it what to do next if there is no automatic protocol.
Common examples and types of IoT devices
The Internet of Things is a somewhat elusive term since it covers various devices and sensors. Several subcategories carry out specific tasks for multiple uses and industries within it. Here is a brief look into how IoT devices are present in our everyday lives.
