Wireless Sensor Network (WSN) is the latest technology which provides the best and cheaper solution for a broad range of applications from healthcare to agriculture to environmental and military operations. India is basically a country with sufficient natural resources and focussed on agriculture contributing to its economy and socioeconomic status. In the agricultural environment monitoring area, WSN plays a major role because of its cost-effective and comfortable deployment of WSN. WSN is in need to minimize the energy consumption through idle, transmission, etc. It requires additional energy efficient technique with data accuracy leads to long life for monitoring agriculture field. A powerful tool that can generate vast and diverse data including agricultural datasets is Association Rule Mining (ARM). A topic that is of attention in data mining of late is ranking of association rules. This work deals with agricultural sensor network which measures temperature, soil moisture, humidity and ARM based on ranking.
