ARM based remote monitoring and Control System for environmental parameters in greenhouse

The work is implemented for remote monitoring and control of greenhouse parameters with the help of sensors and GSM communication. It overcomes the disadvantages of wired and wireless constraints such as complicated wiring, difficult maintenance and distance, to monitor and control the applications. The application will have embedded system which consists of ARM7 microcontroller, real time operating system, sensors, GSM modem and control devices to monitor the environmental parameters condition namely temperature, humidity, CO₂ concentration and light intensity in greenhouse. The threshold levels of the sensors will be set with the help of push button keys or remotely via GSM communication mode. By this, environmental parameters in greenhouse can be monitored and controlled manually as well as remotely. The hardware and software modules of the application system are discussed in detail. This embedded application is implemented and tested for its correct functionality. The experimental results show that the developed monitoring system has the following features, such as simple structure, high reliability, good extensibility and flexible configuration. It will control automatically the environmental parameters in every greenhouse and has project practicality and vendibility.
