Optimal plant management system via automated watering and fertilization

Different type of plants needs different amount of fertilization and water. The high or low amount of water or fertilization daily can damage the plant’s roots leading to unhealthy crops. In this paper, a Smart Plant Management System to control the plant’s watering and fertilization based on their optimal growth conditions ranging from temperature to soil moisture presented. A conditional based algorithm deployed into the controller to determine the optimal condition for the plant based on schedule, temperature, humidity and soil condition. The controller will relay information to two pumps for necessary water and fertilization. The system comprises of Bluetooth connectivity to allow user to provide input through phone application based on type of plants alongside optimal temperature, humidity and soil moisture for the plant to grow. The system also capable to monitor the plant life, status, and management history. The selected plant selected for this study is green mustard (Brassica Parachinensis) or called choy sum locally. The performance of the Smart Plant Management system under several conditions to determine their performance in maintaining the plants optimal condition is tested.
