本論文使用二極式印刷電極來設計一個氯離子濃度感測器，該感測器可應用於水中氯離子濃度檢測，以評估純水之品質、評估廢水中之溶解礦物質濃度、預估水進行化學分析時之樣品使用量、及檢核化學分析結果之正確性。本論文所提出之氯離子濃度感測器設計是採用可程式化邏輯閘陣列(FPGA)、電荷轉移電路、以及類比數位轉換電路(ADC)來開發完成。

In this paper, we use two screen-printed electrodes to design a chloride ions concentration sensor for the water quality detection. The chloride ions concentration sensor, which is designed by a Field Programmable Gate Array (FPGA), a charge transfer circuit and a 12-bit analog to digital converter (ADC), can be used to evaluate the quality of pure water, to evaluate the concentration of dissolved minerals in wastewater, to estimate the number of samples used for chemical analysis of water, and to check the correctness of chemical analysis results.
