Advanced WSN Based Green House Monitoring and Controlling with GSM Terminal

Wireless Sensor Network

This paper represents the modeling and optimizations on advanced GSM (800-900MHz)-WSN (IEEE 802.15.4) based greenhouse monitoring and controlling with SMS terminal. The proposed system includes sensor station and base station terminals performing various conditioning functions. PIC18F4520 controller is used for better conditioning of climate parameters in the greenhouse. The sensor station is equipped with several sensor elements including temperature, humidity, light and soil moisture. The communication between the sensor station and base station is achieved via ZigBee wireless modules and base station to user is achieved via GSM network. By employing GSM Terminal access to proposed system, field parameter has been accessed by using conventional SMS facility. Solar panel is employed to energize the whole assembly in greenhouse. The wireless sensor stations in the greenhouse measures temperature, humidity, light, soil moisture etcetera with their relative standards. By relating the variation in set points of sensors, proposed parameters in greenhouse has been conditioned.
