Development of a data acquisition and greenhouse control system based on GSM

Abstract

This paper explains the design and implementation of electronic system based on GSM (Global System for Mobile communication) for controlling the climate parameters by SMS (Short Message Service) in greenhouse. The main purpose of this system conception is the remote control of the climatic parameters that influence the production in greenhouse (Temperature, relative humidity of air and soil moisture). Several sensors and actuators are installed and connected to a management and acquisition card. These sensors provide relevant information that is used to control ventilation, heating and pump by SMS. The procedure used in our system provides the owner with a remote control avoiding the needed to perform the control actions on site. The developed system in this paper is ideally suited for agricultural greenhouses in Morocco. It is simple to be installed and used by farmers who do not have knowledge in computer skills. Besides, most people use their cell phones to communicate and send messages. Thus, in our system, with a simple message, all farmers can control their greenhouses from a distance. They can know the status of their greenhouse climate at any time (temperature, humidity...) and can control actuators to adjust these parameters (fan, heater, vent, drip irrigation...). Thus, we have developed a graphical interface using LabVIEW software for the local acquisition, monitoring with PC and storage of all data through the card PCL812PG.

Soil Moisture Based Irrigation Test in a Remotely Monitored Automated System

“…Further work by Rahali et al [6] supports this claim that electronic system achieves the control and remote monitoring of greenhouse solutions, in particular drip irrigation stations. This system uses a preprogrammed setup to collect real time data in the environment through sensors.…”

“…Graphical user interfaces (GUI) uses LabVIEW that was designed to acquire and monitor different climatic conditions. This allows the user/farmer to control farming activities from anywhere automatically without manual labour intervention [4,6]. Zigbee wireless network is mostly used in greenhouse for monitoring and controlling system environmental parameters.…”

“…Solenoid valves control rate of flow. The valves are controlled remotely by text instructions using SMS [6]. Sustainability of vegetable production requires optimization of fertilizer and water use to maintain high yields and profitability.…”

“…The system will use microcontroller, LabVIEW software for the interface connected to a PC for monitoring and GSM (Global System for Mobile communication) for remote communication with the system which is convenient for farmers through text SMS. The setup is selected for its real time, user friendliness, flexibility and availability at low cost [6]. Moisture sensors which are considered to be the most efficient instruments for their real time moisture monitoring will be incorporated.…”

Environmental Monitoring and Controlling System for Mushroom Farm with Online Interface

“…This system is more complicated compared to the previous system, as it does not only allow data acquisition, it also allows user to control humidity, temperature and soil moisture via SMS (Short Message Service). The temperature sensor used is LM35DZ and the humidity sensor used is HIH-4000-001 [14]. Some effort in the design and implementations of an indoor environmental monitoring system based on Arduino microcontroller had also been made.…”
