plants under greenhouse conditions, environment, development and growth than the average speed of test trees planted in the natural environment Greenhouse gardening carries multiple advantages—not just for your plants, but also for the gardener Here are four of them: ✓ Protected Environment: Unlike backyard gardens exposed to changing weather conditions and the threat of pests, a greenhouse creates a safe haven for plants—from fragile ornamentals to hardier vegetables In this consistent environment, not only are plants protected, but also gardeners don’t have to make emergency preparations for blizzards, high winds, heavy rains and the like This isolation also limits exposure to insects and animals that may harm or destroy your gardening efforts ✓ Multipurpose Environment: Under the roof of your greenhouse, you can tend to a variety of plants—vegetables, fruits, herbs, flowers and more Because they aren’t planted directly into the soil, this assortment can be combined in one place without much restriction An added bonus is that a greenhouse can function as a storage space, as well as gardening space Tools, implements and accessories can be organized close to where you’ll be using them 77 ✓ Save on Grocery Bills: Growing your own fruits and vegetables—in a backyard garden or in a greenhouse—will help you reduce your food bills Prices of fresh produce are affected by weather and transportation costs that often fluctuate But opting to your food gardening in a greenhouse gives you more control over the costs, as well as the control to grow your favorite types year round ✓ Control of Produce: Greenhouse gardening isn’t just good for your budget; it’s also good for your health Growing your own in a greenhouse means you have complete control over the growing environment Unlike commercial farms, you don’t have to use pesticides and toxic chemicals to improve growing conditions and increase production Greenhouses give gardeners the option to cultivate fresh, delicious produce without adding pesticides that could harm them or their families 78 CHAPTER 5: CONCLUSIONS AND FUTURE DIRECTIONS 5.1 Conclude Our graduation project is an IoT agricultural application systems, The name is the “Clean Vegetable Garden” In addition to vegetables, the system can be applied to many other areas Process of understanding and implementation of the project, the group has access to many IoT powerful processors such as Raspberry, Intel Galileo Gen, Arduino, Msp340, but the team chose Board Arduino, Arduino Ethernet Shield, Actuators, are components available, well handling system requirements set out About the Server system, there are now many IoT development platforms such as Thingspeak, Ubidots, Xively, Carriots, Bosch Software Innovations Suite, Nearbus… At the first, our team wrote a Web Server to send data to: Figure Web interface 79 Also implemented on many different servers such as Nearbus, Xively, but because the server does not meet the needs of the topic should finally decided to choose Cayenne, simple, easy to access, friendly and responsive Meet the requirements of the system The project has designed, successfully built mini vegetable garden model with the functions: ❖ Collection of environmental parameters including temperature, humidity, soil moisture, rainfall ❖ Send parameters to Server over Internet and software via Internet ❖ Server storage, management of data on the Cloud ❖ Web Server interface is quite intuitive, easy to use ❖ Voice control system ❖ The system warns the users ❖ Data transmission and control over the Internet meet real-time well ❖ Remote control system Development: Improve service quality with higher QoS levels More security for the system Integration of sensors to better monitor the parameters of the farming environment, more efficient and economical planting Software that controls more functions, via wifi rather than Bluetooth, is more eye-catching.Add automatic functionality on the software 80 And in specially, we need to come up with an algorithm for solving problems related to commercialization Our team make had wrote a website displaying the ease of operation on the internet and introducing the project Link website: www.green-house.cf Figure Wesbite to display my project [7] 5.2 Future directions The thesis presents the methodology for the most optimal control and optimization of the greenhouse model and selects the optimal control protocol and the best accuracy For the future, an algorithm to meet issues related to commercialization is needed, especially the SVM For empirical research, building a smart greenhouse model to collect data and accurately assess the pros and cons of the Support Vector Machines algorithm provides Intelligent greenhouse systems need to be good at controlling and monitoring, using the MySql database and the SVM algorithm will make the greenhouse smarter and easy database lookup Easier and more homogenous 81 REFERENCES [1] Massimo Banzi : "Getting Started with Arduino" [1] Brian W Evans, "Arduino Programing Noterbook", Creative Common, August 2007 [2] Đặng Trung Thành:
