Exploring the hardware requirements

Before moving forward, we will first look at what types of development boards and sensors are required to accomplish the project. We aim to use a board that provides Wi-Fi connectivity, is small in size, and is low in cost. If we talk about Wi-Fi-enabled development boards, then there are a lot of organizations providing them, such as Arduino, the ESP32 series, and the ESP8266 series. Arduino development boards such as MKR Wi-Fi 1010 and MKR Wi-Fi 1000 are expensive compared to ESP32 and ESP8266. Now, we have two options: we either go with ESP32 or ESP8266 and leave the Arduino development boards. In this project, we will be using the WeMos D1 Mini, which is part of the ESP8266 series. Although the ESP32 series offers similar features, it is equipped with Bluetooth Low Energy (BLE) connectivity, which is not currently compatible with this project. Thus, we have opted for the ESP8266 series development boards, which are not only compact in size but...
