IoT-Based Plant-Watering Robot for Greenhouse Seedling Cultivation
Efficient and evenly distributed irrigation is a crucial factor in greenhouse seedling cultivation. However, conventional sprayers utilization is often associated with water wastage and uneven water distribution. In this study, an IoT-based automatic plant-watering robot was designed and developed, which controllable via Arduino Cloud and equipped with an automatic push button to enhance operational flexibility. The robot development was performed using prototype-based design approach. The robot was built using an ESP32 as the main microcontroller, a 12V water pump, an L298N motor driver, and a push button used as a motion limit sensor. The results demonstrated that water usage was more efficient with the watering robot, achieving savings of 81.67% compared to the conventional sprayer method. The watering process performed by the robot was proven to be more controlled and evenly distributed, although slightly higher moisture levels were observed in the center area compared to the left and right sides. In the watering time evaluation, 2 minutes were required by the robot to match the volume of water dispensed by the sprayer in 1 minute, due to the intermittent watering pattern employed by the robot. These findings highlight potential application of the proposed technology in greenhouse seedling cultivation, thus promoting better trade-off between sustainability and economic benefits in the agriculture sector.
