Comparative analysis and practical implementation of the ESP32 microcontroller module for the internet of things

This paper discusses the Espressif Systems latest product ESP32 designed for Internet of Things and embedded system related projects. The ESP32 is a low-cost, low-power system on a chip series of microcontrollers with Wi-Fi and Bluetooth capabilities and a highly integrated structure powered by a dual-core Tensilica Xtensa LX6 microprocessor. This paper provides a comparative analysis of the ESP32 with some other market competitors and introduces the microcontroller specification, features and programming details. A portable, wireless oscilloscope based on the ESP-WROOM-32 and a mobile application is described in detail as an example of successful practical implementation of the device.
