The Internet of Things (IoT) is a network of components (electrical equipment) that can communicate with one another without the need for human intervention. It is typically deployed in islands of diverse systems.

What exactly it is?

Lights, thermostats, TVs, and motion detectors are just a few of the smart home devices we have. The Internet of Things, or IoT, refers to the automatic connection between these objects.

For example, if the motion detector detects movement while no evidence of family members’ presence (watches, mobile, etc.) are present, an alarm is triggered. Another example of an automation/no human contact event is when the leak detector detects and communicates an over-threshold incident.

1. Manage and monitor your gadgets from distance (smart devices)
2. Create rules that will automate your house, industry, and other systems, resulting in lower energy bills and less human effort.
3. Collect raw data for analytics, and the raw data gathered via various sensors can be used to:

• Predict what will happen in the future, both expected and unexpected.
• In the events, look for any rules.
• Recognizing patterns

But where and how might the Internet of Things help people now?

Home: 

•  Save energy by controlling lights based on motion detection sensors.
• Predict odd events, such as the door opening while you are away.
• Sensors that track leakage/disruptions and alert on mobile phones might help you avoid calamities.

Environment:

• Air pollution and forest fire detection
• Early earthquake detection and distributed control in tremor-prone areas
• To protect wildlife, a tracking collar system has been developed.

Industry:

• Predict equipment failures and schedule servicing visits.
• Keep an eye on the numbers and send out alerts when they reach certain levels (with the sensors installed in equipment)
• Process payments for public transportation, gyms, theme parks, and other services based on the user’s location, activity, and duration.

In industries such as government, education, finance, logistics, agriculture, and transportation, the smart city IoT solutions have become a catchphrase. In the consumer sector, it has made amazing progress. While the notion is still evolving, it has already altered how people, technology, and devices interact.

Smart City concepts must be comprehensive, pluralistic, and citizen-centered, with an emphasis on enhancing services and addressing major urban concerns. There are three primary reasons to invest in smart city IoT solutions: to become more productive and cost-effective, to boost revenues through improved public infrastructure operations, and to improve sustainability and compliance with environmental regulations.
