Smart Living: A Critical Analysis of IoT-based Home Automation Using NodeMCU and Blynk

Abstract

The internet of things, or IoT, links tools and gadgets to the internet so they may be remotely managed by websites and smartphone applications. It also allows for the control of instruments and tools using codes and algorithms to solve artificial intelligence problems. Our tools, equipment, and devices are connected to Wi-Fi or Ethernet connections, and we may control them via internet websites or smartphone applications if we choose to build sophisticated systems with Python algorithms. That's the Internet of Things put simply. The Internet of Things (IoT) can be used for more than just controlling lights and other household appliances in a smart home. Beyond controlling lights and other household appliances, the Internet of Things (IoT) can also be used as a security system or an industrial system. And IoT technology can be used to further ideas. Numerous lamps can be seen in large industrial facilities or government buildings. Sometimes, workers neglect to switch them off at the end of the workday. This study offers a way to reduce energy consumption by enabling the building's lighting to be controlled by the security system using his smart home's Blynk app. With a certain electrical installation, switches placed throughout the building may simultaneously control the lamps and the Blynk application. This study offers a basic smart home prototype, or a cheap and simple method of controlling loads via a Wi-Fi connection in general.
