The system is built using a soil moisture sensor and a Raspberry Pi-controlled water pump. The soil moisture sensors measure the amount of water in the soil to maintain consistent and ideal soil conditions for plants. In this project, the soil moisture sensor interfaces with the Raspberry Pi, which then detects the dryness in the soil; if the moisture level is very low, this implies there is a need for watering the plants. It signals the Raspberry Pi about the moisture level being too low. The Raspberry Pi turns on the water pump to start watering the plants until the soil achieves a sufficient moisture level and then turns off the water pump.
The benefit of using smart home gardening is that it prevents our plants from getting too dry. The moisture is kept at the perfect level for our plants and we end up using less water!
