For this smart watering system project, we worked in groups. My group consisted of four people: me, Ahnaf, Zammir, and Falah. During this project, we encountered an error with the relay while working on it. After that, we replaced the relay and it started working again. So, the smart watering system works by watering the plants when the soil is dry; it can detect this because there is a sensor that measures the moisture level of the soil.
