Internet of Things (IoT) has recently gained popularity in the tech industry and beyond. The basic definition of IoT is an ecosystem of physical devices that are connected and can be accessed from the internet. These physical devices are embedded with sensors which collects data from the environment they are placed in; analytics is applied to the data to derive meaningful and useful results.
Though the term Internet of Things has not been around for a long time, the concept of IoT has been around for quite some time. In fact, the concept of connected devices can be dated to the pre-internet age where we can reference the first electromagnetic telegram in 1832. The invention of the internet created the platform for interconnecting many devices, starting with the computer to the embedded devices which lead to the invention of IoT. The history of IoT cannot be accurately traced in time but it is grossly coupled with the invention of the internet.
IoT devices can largely be classified into three categories; those that collect and send data, those that collect and act on the data; and the hybrid that do both. The IoT devices that act on the data brings about the subject of artificial intelligence (AI). AI is a broad area that closely relates with IoT. The classification of these the IoT devices based on the categories defines the complexity of the design. This is also influenced by the application of device.
The amount of data collected by the IoT devices brings about the issue of data security and privacy. The discussion around IoT security has heated with some arguing that privacy is highly comprised. However, sustainable and reliable solutions on IoT security continue streaming into market for testing.
