Development of Automatic Plant Irrigation System using Soil Moisture Sensors for Precision Agriculture of Chili

In agriculture, water management is crucial to reduce the amount of water used for irrigation. This study aims to develop an automatic plant irrigation system to be implemented in the Greenhouse of the Department of Computer Science, IPB University. The system is made of solenoid valves and soil moisture sensors whose amount is adjusted to the number of plants. This automatic plant irrigation system was created to support the development of smart and precision farming in Indonesia. Irrigation is done automatically and precisely for each plant by using a solenoid valve and a relay. The system prototype has been tested with different soil moisture values. Experiment results show that the prototype has successfully read the soil moisture value and can do the irrigation properly according to the specified functional requirements.
