Greenhouse Remote Control and Monitoring System

Abstract

Greenhouse offers a protective environment for crop production while allowing natural light transmission. Continuous control and monitoring of the greenhouse parameters is a pivotal part in the production practices. This paper aims to tackle the weaknesses of the current system in terms of costly and complex equipments, high maintenance cost, instability and inability to control and monitor from remote location. It describes how the innovative greenhouse control system can be characterized as an event-based system, where every control actions are primarily deliberated compared to the events formed by instabilities from surrounding elements. Proposed paper offers a costs-saving solution with low maintenance required, as well as producing a great performance results. This system eliminates the over-dependability of the industry on human workforce. Basically, the system will continuously measure, control and monitor two of the most important parameters, temperature and light intensity. Hardware such as LM35DZ temperature sensor and light dependent resistor (LDR) used to measure and send input signal to the controller. On the other hand, heating resistor and bulb are receiving output signal from the controller to regulate the controlled variable. The software-based controller able to control the processes while eliminating steady-state error and also give fast response to any changes in the input, or in the effect of disturbance into the system.
