Story

Our team decided to work on this project to allow urban farmers in Singapore to have an automated plant watering system. This will reduce manpower load, ease the workload of the farmers and help to save water by watering the plant only when it is needed and how much is needed.

It starts by turning on the device, the program would be able to detect the moisture level in the soil and water the plant depending on factors such as sunlight level and plant moisture level on whether to water the plants.
