Abstract: A wireless sensor network is a wireless network consisting of spatially distributed autonomous devices using sensors to monitor physical or environmental conditions.  The components are selected, which is depends on agriculture application. The WSN node is used for sensing, processing and communicating. These nodes are cluster head and slave. The need of protocol is to define rules for each step and process during communication. The protocol is set of rules. The main job of protocol in our project work is to maintain the lifespan of WSN nodes. In this proposed work, arduino based WSN node system are designed and developed for experimentation. The sensor such as moisture, temperature, humidity and light are used for agriculture application. The data collected from these sensors are stored in memory and transferred to PC using RF modules. A technique based on modified LEACH protocol is used to maintain store energy in WSN nodes. This in turn, enhances the lifespan of cluster head WSN node. The sensor nodes are powered by rechargeable batteries. This system will help farmers to monitor their crop with performance parameter measured and displayed. It will enhance productivity of crops.
