Prueba PZEM-004t con Arduino UNO + Shield Ethernet W5100
I was really a bit away from Arduino in my last tests, but I decided to buy and try one of the most famous or used plates, the Arduino UNO with the Shield Ethernet W5100 both were so cheap that it was impossible not to buy them.

Connections
Mounting
Arduino IDE Code
Although this case will not use the Ethernet Shield features such as LAN communication and microSD, it must be borne in mind that the Ethernet Shield works by SPI bus, which uses pins 10 and 11 of the Arduino UNO, for this reason and to avoid conflicts SoftwareSerial library that generates a new port to communicate with the PZEM-004T uses the rx (8) and tx (9) pins.

Serial Terminal
- Output port UART0 Serial0.
