High-Speed Ethernet-Based Voltage Acquisition Architecture for Long-Distance Industrial Testing
Ethernet-based DAQ samples multi-channel 0–5V signals at 10 kHz, compresses on MCU, and sends UDP packets via W5500 up to 100 m.

Project description
Overview This system addresses a common limitation in industrial test environments where high-speed analog signals must be acquired over distances that exceed the practical limits of USB or direct analog transmission. By digitizing signals near the sensor, compressing them in real time, and transmitting them over Ethernet, the design prioritizes signal integrity, timing determinism, and scalability. Main Content At the core of the system is a multi-channel SAR ADC that samples pressure sensor voltages at rates far exceeding the required 10 kHz per channel. Rather than relying on…
