7.1 Introduction
IoT is an extremely large network; it contains and consists of each electronic device such as mobile phones and home phones, connected home appliances, connected vehicles, and many more smart electronic objects. IoT has emerged as one of the most important technologies of the 21st century. IoT is now being used in every research area, security system, health science, or manufacturing of any objects or devices[1]. In short, we can say that IoT has made our daily life more reliable and easier. The most important features of IoT include receiving, storing, sending, and accessing different sensor data in real time from anywhere. The sensors are basically used to collect the information, such as time, temperature, humidity, body mass index (BMI), acceleration, and many more depending on the different kinds of sensors [2]. The sensor receives and stores information in real time and then sends that information to the cloud by using any kind of Wi‐Fi module such as D1 mini NodeMCU, ESP8266 NodeMCU, or Bluetooth modules HC‐05, with the ...
