Abstract

An implementation of a reconfigurable FPGA (Field-Programmable Gate Array) is proposed for digital control and acquisition tasks associated with a water quality sensor calibration system. The system permits the water quality (WQ) sensor auto-calibration based on FPGA control of different actuators (pumps and electrovalves) and of WQ data sensor acquisition, real time WQ data processing based on real-time controller capabilities and wireless data communication. Elements related with the power consumption of the calibration system are also presented.
