A Hybrid Green House Management by Power Intelligent Device / Wireless Networking (Polyhouse Automation System)

摘要

This paper represents the modeling and optimizations on advanced GSM (800-900MHz)-WSN (IEEE 802.15.4) based mostly greenhouse observation and dominant with SMS terminal. The projected system includes device station and base station terminals acting numerous acquisition functions. PIC18F4520 controller is employed for higher acquisition of climate parameters within the greenhouse. The device station is provided with many device components as well as temperature, humidity, light-weight and soil wet. The communication between the device station and base station is achieved via ZigBee wireless modules and base station to user is achieved via GSM network. By using GSM Terminal access to projected system, field parameter has been accessed by exploitation standard SMS facility. solar array is used to energise the complete assembly in greenhouse. The wireless device stations within the greenhouse measures temperature, humidity, light, soil wet etcetera with their relative standards. By relating the variation in set points of sensors, projected parameters in greenhouse has been conditioned.
