WSN in coffee cultivation

India ranks sixth in the world in terms of production of coffee. As India being predominantly a tea consuming nation, about 80% of the country's coffee production is exported. The cultivation of coffee is primarily in the southern states of India and depends predominantly on the south west monsoon. Due to the current change in the climate patterns, artificial irrigation is essential to boost the productivity. Various studies have proven that the crop experiences water stress during dry season and this inhibits the blossoming of buds, consequently reducing the yield considerably. Wireless Sensor Network (WSN) assists in monitoring the soil and environmental parameters through appropriate sensors. Soil moisture sensors and soil electrical conductivity sensors can help to detect the water and nutrient deficit in the soil and appropriately apply water and nutrients through drip irrigation system. A leaf wetness sensor can also be used to estimate the transpiration and photosynthesis rate besides predicting the risk of bacterial and fungal attacks. The irrigation can be scheduled and automated based on the prevailing field conditions.
