Therefore, development of the low-price sensors will reduce the cost of the automatic control and monitoring system, and thus lead to an effective management of the wastewater treatment system. This study will design and fabricate a DO sensor at the early stage. The work will involve the I/O signal conditioning, selection of the approp畜牧廢水感測器自動化livestocksensorautomation
