Energy Monitoring using ESP32 and power meter PZEM004T v3.0

A microcontroller ESP32 reads data from PZEM004T using modBus protocol via serial communication. This data is then sent to the server using HTTP protocol with some energy parameters (Voltage, Current, Power, Energy, Time) via WiFi communication to be recorded to a table from database. These charts show the last 300 records from the database.
