An Energy Optimized Wireless Sensor Networks using Automatic Irrigation system

Now a days Wireless Sensing Technology (WSN) is booming in this scientific world. As the technology is growing and changing rapidly, WSN helps to upgrade the technology. Low cost, low power consumption and applicability of multi-function sensor nodes are the main advantages of WSN. ZigBee plays a vital role in controlling the WSN. The proposed Irrigation Management system (IMS) identifies water deficient locations by detecting the vital information about the soil and informs the farmers about it via alarming unit or a text message. The receiver node collects the data from field sensor and processes them to take decisions. To optimize the energy the Time Division Multiple Access (TDMA) scheduler assigned the time slots for each node and those sensor nodes turn ON/OFF their radio according to the schedule to save energy. If the collected data are less than the threshold value, the receiver node will inform the controller to switch ON/OFF the pump motor, Buzzer, Fan.
