Automatic Soil Irrigation System using Internet of Things

Efficient use of water resources in agriculture is extremely important for sustainable agriculture. The present paper proposes a novel automatic soil irrigation system to minimize the usage of water based on the actual content of soil moisture. The system integrates moisture sensors, a microcontroller and an automatic valve controller. The proposed system is precise in irrigation, saving water and providing the crop with the optimal amount of water. Experimental findings prove the efficacy of the system to manage soil water to the required level without much manipulation by man. It is scalable and may be utilized in diverse farm settings, and it achieves cost saving as well as environmental sustainability. The data is processed by IoT device that triggers automatic watering the instant the water level in the soil drops below a set reading. The system can be remotely accessed and monitored via web or mobile applications in a bid to enable farmers to efficiently manage watering.
