Abstract
ABSTRACT Hydroponic is one of growing plant method without soil. It use water as the planting media. Curently, hydroponic method is being popular in Indonesia because it is higienic, get more crops, environmentally friendly and low cost production. Hydroponic life is depends on the nutrients in the water. One of the most important of the hydroponic method is pH level of the water. The standard of pH level which used to grow a plant is in the range of 5.5 to 6.5. To balancing the standard of pH level, pH up liquid and pH down liquid will be needed. But it is dificult to meansure the pH level on the standard range while adding the water. It would be very helpfull if there is a device that can keep the pH level in the desired range and can be monitored by android devices or computer, because plant need a stable pH level. Based on this problem, this project will be developed automated device for mixing pH up and pH down liqud so the level of pH will be keep in the desire range using pH sensor and Arduino microcontroller. A pH sensor is an electronic device that can measure pH level. The arduino microcontroller will send data of pH level into the Thingspeak IoT server. After data send to the Thingspeak IoT server, the user can see the pH level by smartphone or PC. If pH level is under the range, the arduino will drain the pH up liquid using Micro Water Pump DC, and vice versa until the pH level is in the range.
