SUZANA – automatic irrigation system

The prototype of an automatic irrigation system is designed for efficient water management on agricultural land without access to electricity and water supply networks. The system consists of three main parts: irrigation, water accumulation and power supply. The soil moisture is monitored by a sensor, and based on its readings, an electromagnetic valve automatically opens or closes the water flow. In the absence of a water supply, an electric motor pump can draw water from a nearby source and fill the tank, monitored by a water level sensor. The system uses a solar panel as an energy source, and the energy is stored in a battery so that the system can operate even when there is no sun. The control unit connects all parts, receives data wirelessly and automatically controls the valve and pump according to a given logic. The system is designed to save energy, i.e. the valve operation is prioritized, while the pump is turned on only when there is enough available energy.
