Solar-powered automatic plant watering system with moisture sensor using Arduino Uno

This study utilized applied experimental research to develop a Solar-powered automatic plant watering system with a moisture sensor using Arduino Uno.The device aims to automatically water the plants by detecting their moisture content, encourages water conservation, and helps users water plants.To improve soil management efficiency, a solar-powered plant watering system and soil moisture sensor have been developed using materials such as Arduino Uno R3, a mini water pump with a small pipe, a mini solar pane, a soil moisture sensor, jumper wires, batteries, 5V relay module, a 16x2 LCD for the automation, while a charge controller, and a plastic container as the main base of the product.Twenty-three participants took part in the survey to assess the usefulness and effectiveness of the system, offering helpful suggestions for improvement.The results show that the system functions well at its level and that it has the potential to support sustainability by keeping the soil hydrated.Moreover, the automatic watering system can shorten the time it takes to water the plant.The researchers also discovered that the wiring and coding play the most significant role in the device's effectiveness.A minor alteration to these components can significantly affect the device, particularly the pump's code, to improve the water intake, thus lessening the time to water the plants.This study promotes technological advancement and environmental awareness since it is essential to incorporate sustainable practices.
