Wireless sensor based control system in agriculture field

Abstract

In an advanced agriculture the consumption of water is very high. Due to the developments in technology, efforts are being channeled into automation of irrigation systems to facilitate remote control of the irrigation to optimize crop production and cost effectiveness. In agriculture field, the current agricultural practices need to intensify the rate of food crop production for the rate of population growth with available resources. This proposed work describes the automated system to make effective utilization of water resources for agriculture and crop growth monitoring using GSM. The effective utilization of drip irrigation process is improved by using the signals obtained from soil moisture sensor. The output signals of the sensors are coordinated by the microcontroller and transmitted to the user with the help of GSM Modem. Irrigation is the process of artificially supplying water to land where crops are cultivated. Traditionally hand pumps; canal water and rainfall were a major source of water supply for irrigation. This method has led to severe drawbacks like under irrigation, over-irrigation which in turn causes leaching and loss of nutrient content of soil. The optimized water use for an agriculture crops has been achieved successfully by this systen. The system that can report data to the cultivator remotely and allows to control the process effectively with GSM.
