碩士 === 國立虎尾科技大學 === 電機工程系碩士班 === 106 === This paper proposes a hydroponic system using fuzzy logic control. Regulating electrical conductivity and pH of nutrient solutions. The system can detect the EC value and pH value of the nutrient solution through the sensor at any time and pass the fuzzy control method. Control the working time of the adjusting solution pump. The purpose is to increase and decrease the EC value and pH of the nutrient solution. Maintain the EC value and pH of the nutrient solution. Maintain normal plant growth. The control system uses the Raspberry Pi3 development board to achieve and solve the problem of EC value and pH adjustment of the nutrient solution. The output is the ON/OFF operation time of the pump calculated by the fuzzy control. Meet the set value with the appropriate adjustment.
