How to Read Modbus Serial/RS485 Device Data in NORVI ESP32 Based Industrial Controller |

In this video, we explore the NORVI ESP32-based Industrial Controller "NORVI GSM-AE04-V-G" and demonstrate how to read data from an XY-MD02 Modbus Temperature and Humidity Transmitter using the Modbus RS485 protocol. Since the controller is based on the ESP32 platform, we can easily program it using the Arduino IDE.

This industrial controller comes with built-in hardware to communicate with Modbus devices directly—no need for additional hardware or converters.

Below, you'll find the purchase link for the controller, along with the GitHub link to access the code used in this video and the connection diagram.
