The aim of this research is developing automatic watering and hydroponic nutrients.The purpose of this research is to design,build and test the system to be able to do the watering,hydroponic nutrients drain automatically,and to fog the plant environment,also to monitor the environmental temperature in the plant house.The method used in the research of Automatic Watering System in The Plant House-Using Arduino Board is experiment technique.Some of the steps that need to be considered,namely the design stage,the stage of development/manufacture,and installation phase.Next is the testing of the product that has been made by testing some variables that have been previously specified.As a result,the system can do the watering,drain hydroponic nutrients,and perform automatic misting with a working voltage of 208-214 VAC and 15 VDC,as well as a constant Arduino pin voltage of 4.8 VDC.The system can also display the current state of the soil moisture status and the temperature of the greenhouse.By performing tests on crops,showed growth of plants in the hydroponic method is faster than with conventional cultivation methods.
