Desde el punto de vista del hardware, utilizaremos algo muy sencillo: un nodemcu con un sensor analógico de humedad y una pantalla oled. 96 Inch OLED Display WiFi+Bluetooth CP2102 Internet Development Board for Arduino ESP8266 NodeMCU: Computers & Accessories. This document is intended to help you set up the software development environment for the hardware based on the ESP32 chip by Espressif. In order to facilitate the interaction with the display, we will need to install a library that supports the mentioned display model and can be used on the ESP32.
