The advancement of Internet technology has resulted in an increased role of Internet of Things (IoT) technology in our daily lives, including its application in agriculture. It enables users to monitor operations in real-time. This paper presents an automatic plant watering system through sprinklers on an area of 119 square meters in which trees and shrubs are already planted with an area of 92 and 27 square meters, respectively. The water supply is stored in a 5-meter high reservoir, utilizing potential energy to determine the fluid pressure. The results were calculated to determine the number of sprinklers that can be used effectively without the need for water pumps in order to reduce costs. The system has 2 operating modes: MANUAL and AUTO, processed by NodeMCU microcontroller. It can operate according to predefined time and conditions. The sprinklers are controlled by solenoid valve, using soil moisture and water level in the reservoir as primary factors. The system can control and display real-time data through the Blynk mobile application and notify users of its operation via the LINE messaging application. The system requires the soil moisture to be less than 70% and the water level in the reservoir to be above 30% in order to function. In both modes, the experimental results demonstrate that the system can effectively supply water to plants and accurately notify the users.
