What is IoT?

Internet of Things (IoT) is a giant network that involves various elements that work together to collect and share information, as well as to process data, to produce actionable results that are useful for different purposes. It is a catch-all term that refers to the interconnection of objects or “things” such as electronic devices, digital and mechanical appliances, and the like. IoT collectively pertains to the system of processes, and everything else involved, that take place whenever everyday objects or special gadgets are connected to the internet and to each other for a specific purpose.

How Does IoT Work?

In a nutshell, the Internet of Things is basically just inanimate objects communicating with each other with a common goal in mind. To easily grasp how IoT works, simply think of it as the process of leveling up a basic thing by transforming it into a much more useful tool through the use of the internet and smart connectivity. Instead of doing tasks manually, IoT allows people to automate actions for the purpose of convenience, efficiency, and productivity.

The devices involved in the process are categorized into two: General devices and sensing devices. General devices are the gadgets or appliances that serve as the main component when it comes to data hub and information exchange. Sensing devices on the other hand are composed of sensors and actuators that are responsible for performing in-device functions like the measuring of humidity, temperatures, light intensity, and other activities that gauge particular circumstances. The results extracted from the sensors and appliances are received as actual data by a processing node or gateway. Once the information has been processed in the node, a back-end network known as cloud will receive the processed data. The cloud is the IoT’s network that serves as the platform for all general devices to interact and communicate with. At this point, information can now be stored securely and passed onto the next step for analysis. This phase analyzes the data gathered from the general and sensing devices so it can produce a solution that will be of great help to companies utilizing the technology.

Another outstanding IoT solution is the availability of handy medical devices and equipment which people can actually use independently even without the direct supervision of a health professional. These devices help patients who have chronic illnesses to reduce medical costs by staying and continuing treatment at home. Smart inhalers are beneficial to patients with asthma or chronic obstructive pulmonary disease (COPD). It can track medication use, alert patients to take medicines, provide advice to improve patients’ inhaler techniques and adherence to medication plans, and provide insights to causes of symptoms. Smart inhalers can also alert doctors when patients are not following their medication intake, and this is useful especially in the era of Covid-19 when doctors have difficulties making regular contact with patients.

Automated insulin delivery systems (AIDS) work in conjunction with continuous glucose monitors (CGM) that constantly monitor blood glucose levels to determine the amount of insulin needed. AIDS will continuously deliver insulin and the amount is adjusted based on the glucose level measured by CGM. Through IoT’s network, patients suffering from diabetes can safely receive medications that are of the correct measurements. Diabetes makes a person’s bodily reactions sensitive so it is important that the glucose levels are closely and constantly monitored. Through the help of IoT devices, diabetic people can live a better life, one that doesn’t experience much stress when it comes to the management of the disease.

There are also mood monitoring IoT devices which work by tracking changes in heart rate, blood pressure, and even movement of the eyes to detect a change in the patient’s mental state. This can help psychiatrists collect more data about the patients’ condition, rather than relying on self-reported symptoms. Mood monitoring devices provide more accurate data which greatly impacts a person’s treatment plan.

4. Monitoring of Environmental Conditions
