Project description

Why This Project Stands Out Many embedded measurement systems stop at data acquisition. This project goes significantly further. It combines: Distributed wireless measurement nodes using ESP-NOW Local high-resolution 16-channel ADC acquisition FreeRTOS-based concurrent task execution Ethernet-based industrial data delivery Custom-designed hardware including PCB, Ethernet interface, and analog front-end Python-based capture and visualization tools The result is not simply a sensor node connected to a network. It is a complete measurement infrastructure designed from the PCB level through to…
