Automatic Water Level Control Tem On Hydroponic Plants Based On Arduino

Abstract

Hydroponic farming techniques are generally carried out by flowing nutritious water into pipes that have been given holes for plants. The water that flows into the pipe comes from a water reservoir (water reservoir) that already contains nutrients. At the beginning of planting the existing water discharge in the reservoir has been adjusted to the needs to flow through the existing pipes. Along with the growth of plants that need water and also the process of evaporation of water, the water discharge in the reservoir will decrease. If left unchecked the water will become less and less, this can cause the pump to deliver water to the pipes not working and nutrients to the plants being disturbed. As an effort to prevent this from happening and to support smart systems in hydroponic farming, this research makes a water level control system in hydroponic water reservoirs automatically using Arduino. The test results show the system is able to control the water flow by increasing the volume of water if the reservoir water discharge is below the 60% level.
