This study presents the development and design process of an automated plant watering system for soil humidity in the potted plants. The study was materialised based on the developed 32-Bit Arduino Uno microcontroller system. Three main transducers used in this project to collect the respective data were soil moisture sensor, humidity sensor and temperature sensor. The LM393 soil moisture sensor and the DHT11 humidity and temperature sensor were placed half the height of the soil in the pot to measure the environment and the surrounding for the soil in the pot. The system was connected with motor pump for irrigation. The motor pump started to water the plants when the soil dried. During this process, the measured data was then being displayed at LCD screen and monitored in real time at GUI created by Visual Basic. The data were displayed in degree Celsius for temperature and for soil humidity in a scale of 0 to 1030. The bigger the scale, the dryer the soil was. As a conclusion, an automated plant watering system was successfully implemented using Arduino Uno to control the soil moisture and capable in monitoring data and analysis the parameters in the garden.
