Circuit Documentation

Summary

This circuit integrates a variety of components to achieve its functionality, including an Ethernet module (W5500), a temperature and humidity sensor (DHT22), an environmental sensor (Adafruit SHTC3 STEMMA QT), a voltage sensor (ZMPT101B), and an ESP32 microcontroller with 38 pins. The circuit is designed to monitor environmental parameters and communicate over Ethernet. The ESP32 serves as the central processing unit, interfacing with the sensors and the Ethernet module.
