A WIRELESS SENSOR NETWORK FOR POLYHOUSE CULTIVATION USING ZIGBEE TECHNOLOGY

The required climatic conditions for the polyhouse cultivation can be provided by using this proposed technique. The Zigbee technology has used for implementing the proposed wireless network. Few of the surrounding parameters of ambient temperature, humidity percentage, light intensity range and soil moisture content inside polyhouse are controlled and optimum conditions for crop growth inside polyhouse can be provided with the proposed model using abrupt actuators used. This model has developed with the mesh topology consists various nodes which are deployed inside polyhouse and are controlled by one central monitoring unit (CMU). Based on the crop the threshold values for the sensors and control values for the actuators during day time and night time are programmed in the CMU and it continuously receives the sensors data from all the nodes, and with respect to the programmed values of crop the CMU sends the controlling data to the actuator node for maintaining constant and required environmental conditions. By using this proposed model the necessity of human effort can be reduced and also the suitable weather conditions for the crop production irrespective of the season can be provided for the maximum beneficiary to the farmer.
