Multi-channel Data Acquisition and Wireless Communication FPGA-Based System, to Real-Time Remote Monitoring

In this paper, a low cost, stand-alone and configurable data acquisition system with wireless communication to remote host is presented. The system allows recording up to eight multiplexed analog signals, with 12-bits resolution in variable ranges and a maximum sampling rate 11,500 S/s for each channel. The realization of the systems was done using FPGA as the main chip, and control multi-channel ADC chip to collect data. The data are transmitted to the host using wireless connectivity technologies Bluetooth or XBee, these data can be displayed and analyzed by computer application. The channels, sampling frequency and transmission rate can be configured by the user.
