Development of Automated Plant Nutrient Control Systems by Arduino Program

Abstract

System nutrient control system Nutrients are mixed with a liquid state (substances A and B). The control system mixes nutrients with plants so that nutrients as appropriate for each plant species grow completely.
The plants used in the study used the plant family Melon. Due to the remnants of the plant that relies on economic oversight and proper nutrients at different stages of growth. The design of the nutrient control system using the arduino program. Design work as 2 systems the system is automatic and semi-automatic. The system can calculate the amount of water used in the nutrient mix and control the EC (Electrical Conductivity: EC). It was found that the work of the nutrient control system for the plant Melon can work under conditions set. The average standard deviation of 0.95% in the control system. This is an acceptable value and the acid - base (PH) in the range from 6.8 - 7.0. This research can be applied to practical use for growing other plants. As a model system for plant nutrients. It can reduce labor costs for nutrient mix and can control nutrients at any time.
