Design of Soil Moisture Control Systems Based on Arduino Microcontroller

Control of soil moisture can save water supply for crops.The soil moisture sensor integrated with the Arduino microcontroller board can be programmed as the control system.Addition of RTC module and SD module tools also make the system as the data logger.The purpose of this research was to developed the irrigation automation system with the control of soil moisture.This system has been integrated with the automation system using the power source of solar energy.Soil texture is sandy clay loam, which is dominated by the sand content of 59.67%.Rainfall during the study was 58.5 mm.The control system with Arduino board, set to keep soil moisture between 0.23 cm 3 cm -3 -0.30 cm 3 cm -3 .The soil moisture in that range was able to be controlled with this system.Land without agricultural cultivation activities when water resources are limited, can be empowered with the application of irrigation automation systems.
