NodeMCU ESP8266 For HOME AUTOMATION (IoT Application Development) The best way to quickly develop an IoT application with less Integrated circuits to add is to choose this circuit “NodeMCU”. It is an open-source firmware and development kit that plays a vital role in designing a proper IoT product using a few script lines. The module is mainly based on ESP8266 that is a low-cost Wi-Fi microchip incorporating both a full TCP/IP stack and microcontroller capability. It is introduced by manufacturer “ Expressif Systems” . The ESP8266 NodeMCU is a complex device, which combines some features of the ordinary Arduino board with the possibility of connecting to the internet. Arduino Modules and Microcontrollers have always been a great choice to incorp...
