碩士 === 龍華科技大學 === 電機工程系碩士班 === 102 === In this thesis, embedded systems and water quality monitoring will be done in conjunction, in order to reduce the cost of system equipment, as well as reduce the control terminal equipment space occupied. In this thesis, Arduino controller via RS485 automatic transmission developed water quality monitoring system. The traditional water quality monitoring systems are mostly PLC combined with RTU. In this thesis, the use of Arduino controller developed automatic water quality monitoring system. This system via RS485 Interface site transmission header, and agreed to join the RS485 MODBUS communications systems to meet the market demand, while increasing system scalability. This system is also combined with a remote server for water quality monitoring. By test analysis, comparing the pH me ter meter display numerical difference between the value of the Arduino controller reads, the future can be applied to remote monitoring.
