Remote Monitoring and Smart Control System for Greenhouse Environmental and Automation Irrigations Based on WSNs and GSM Module

Abstract

This paper depicts the automatic irrigation and environmental monitoring inside the greenhouse based on WSNs (Wireless Sensor Networks) and GSM Module. The system is able to collect information about key environmental parameters, such as temperature, relative humidity, Water level within irrigation water tanks, light ratio, CO2 dosage and soil dryness within the greenhouse. Analog signals from different sensors are converted to digital values by taking advantage of the ability of GSM (Global System for Mobile Communications) to convert analog signal to digital without the use of microcontroller. This information is transmitted wirelessly to the central computer to be processed and decided on by way of applying a simple fuzzy input system to send appropriate digital commands via the digital outputs of the system to regulate the glass house parameters within acceptable limits. The collected data and control commands that are applied in the database are stored to be analyzed for purposes of improving Agriculture.
