How To - Build a Modbus Server from Scratch (ESP32 + Raspberry Pi + SHT41) | BAS & SCADA Integration
In this video, I walk through a complete, real-world example of building a custom Modbus server device from the ground up - from programming in Arduino and connecting the wires all the way to seeing live values on a BAS or SCADA screen. Providing two paths, using an ESP32 and a Raspberry Pi, I interface with an SHT41 temperature & humidity ...
