The term “Internet of Things,” or “IoT,” refers to a network of widely dispersed, online-connected devices that collect and exchange data. People can increase the pro-activity and intelligence of everything thanks to the processor found within the same wireless network. People can create micro-controllers and embedded systems on the Arduino platform. With so many options and affordable modules, dedicated to both personal and professional projects. IoT projects are primarily centered on home automation and smart home applications in the DIY community, but industrial and commercial IoT projects use a variety of methods, including
machine learning, artificial intelligence, not network sensor wire, etc. Any IoT project must have an Internet connection, regardless of its size, whether it is a simple DIY project for a hobbyist or an intricate industrial project. Here are devices of IoT ESP like the ESP8266 and ESP32 useful. The ESP8266 is a fantastic option for engineers looking to add Wi-Fi connectivity to their projects. However, ESP32 is the best option if they want to develop a comprehensive system with Wi-Fi connectivity, Bluetooth connectivity, high-resolution ADC, DAC, serial communication, and more.

Among IoT ESP types, ESP32 has a dual-core CPU running at 160 to 240 MHz, whereas ESP8266 only has a single core at 80 MHz. We are all aware that each processor needs a CPU (core) to serve as the hub for processing all operations. When an ESP32 has two CPUs, it can perform more tasks and work more quickly. Additionally, the manufacturer has specified the CPU’s PRO CPU and APP CPU functions in the name of the component (Protocols and Application). It is challenging to incorporate all the technical details in this essay because the ESP32 has more functionalities than the ESP8266. The list that follows illustrates the advanced technical characteristics of ESP32.

  • Dual-core 32-bit LX6 processor with clocks up to 240 MHz.
  • 520 KB SRAM, 448 KB ROM and 16 KB SRAM RTC.
  • Supports 802.11 b/g/n Wi-Fi connectivity with speeds up to 150 Mbps.
  • Support for both classic Bluetooth v4.2 and BLE specifications.
  • 34 programmable GPIOs.
  • 18 channels of 12-bit SAR ADC and 2 channels of 8-bit DAC
