, Description:FIELD OF THE INVENTION:
The present invention relates to automation control area. The present invention more particularly relates to a solar energy greenhouse temperature monitoring system based on technology of Internet of things.
BACKGROUND OF THE INVENTION:
The greenhouse industries are the fastest growing sector worldwide. The greenhouse separates the crop from the environment, thus providing some way of shelter from the direct influence of the external weather conditions. This enables the production of crop which otherwise could not be produces at that specific location. The greenhouse enclosure enables the manipulation of the crop environment. This asset allows the farmer to improve the cultivation in a way the plants need. It lead to higher crop yield, prolonged production period, better quality, and less use of protective chemicals. The added value per unit area in greenhouse crops is much higher than that in open-field cultivation. In moderate climate zones, energy is needed, whereas in arid zones, the cooling and availability of water is of major concern. The use of materials and energy as well as crop yield and quality can be influenced by operating the adjustable components of greenhouse, such as heating and cooling inputs, window opening, drip irrigation, screening and CO2 dosage. Hence, it can be expected that the way these controls are operated influences the final economic results.
It is indispensable to Know the control variables with a remote sensing system using the GSM. This is because it is almost difficult for human being to manipulate and be present every day near the system. Indeed, remote communication systems are a major component of the policy of modernization and technology transfer, due to the increasing development of mobile telecommunications. Internet of Things (IOT) is the network of physical things embedded with electronic circuits, sensors, software and network connection which enables these things to exchange data from one another. In a world of IOT, millions of things or devices will be interconnected and uniquely identified on the Internet. The Internet of Things allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration between the physical world and computer-based systems, and resulting in improved efficiency, accuracy and economic benefit. Most physical variable relevant in a greenhouse can be measured by automatic sensor.
From last few years, there has been popularity in rise of electronic technology for control of greenhouse. The most important improvement in technology based climate control are found in data logging which means recording the data monitored from the greenhouse. The common problems experienced with using several independent thermostats and timers to control a roof top irrigation led to the development of early electronic analogue controls, also known as “step” controls. These devices made a major contribution to improving the growing environment and increasing efficiency by combining the functions of several thermostats into a single unit with a single temperature sensor.
So there is a need for a remote sensing control system using GSM which can provide real-time environmental information for crop growth and then be transmitted. The system monitors the varieties of environmental parameters in to the greenhouse effectively and meet the actual agricultural production requirements. Devices such as temperature sensor, light sensor, relative humidity sensor and soil moisture sensor are integrated to demonstrate the proposed system. The present system automatically measures and monitor changes of temperature, light, Humidity and moisture level. The quantity and quality of production in greenhouses can be increased and provides the owner with the details online irrespective of their presence onsite and collects environmental parameters inside greenhouse tunnel every 30 seconds. The parameters that are collected by a network of sensors are being logged and stored online using Internet of Things (IOT).
