Solar Powered Automatic Drip Irrigation System (SPADIS) using Wireless Sensor Network Technology

The farmers working in the farmlands are dependent on the rains, river, pond and bore wells. Even if the farm land has a water-pump, most of the time it is being kept stand-still due to non-availability of grid power in the remote areas where the potential of sun light availability is tremendous throughout the year. Increase in agricultural production depends to a large extent on the availability of water and power. If the solar power is harnessed, an agricultural pump can run during day hours without depending on grid power. It is observed that in addition to water and power shortage, the farmers are not aware of the scientific method of irrigating the agricultural land. By adopting a proper scientific method, the farmers can save water, energy, labouring time and production cost. The main objective of this paper is to establish an automatic solar powered drip irrigation system by adopting wireless sensor network technology (WSNT) by integrating Solar Photovoltaic System (SPV), Arduino Microcontroller, Soil Moisture Sensor, Mobile Bluetooth, Water Tank, Pump etc. WSNT employed in this work contributes not only to save energy, water, fertilizers but also ensure uniform watering at right time without manual intervention leading to enhance the quality and quantity of agricultural yields.
