Energy efficient wireless monitoring system for Agarian areas in Indian agricultural system using GPRS module

In recent engineering advances the convergence of internet, communication and information technologies will pave the way for new generation. Currently, distributed wireless sensor network plays significant responsibility in civilizing agricultural production and mitigating the agony of farmers. Soil moisture and temperature sensor are buried at the root zone of the plant. Owing to different climatic condition, Rain water sensor is located at the surface of the soil to deactivate the entire irrigation system during rainy season. The PIC microcontroller is used to gather the sensor information in real time. The data can be acquired and processed by sending and receiving the information from cultivation field. The measured data is allowed for data inspection with cellular internet interface to be graphically visualized through GPRS module. The whole irrigation system is powered by solar photovoltaic panel with battery power management system. The automated irrigation system is tested in turmeric and onion plantation simultaneously for 50 days. Water savings is up to 90% when compared with the present trickle irrigation channel is achieved. By incorporating the automated irrigation scheme, consumption of water and electricity is reduced, further it increases the quality of food grains and the yield of crops.
