Abstract: Most people in Thailand make most of their money from farming. But it's getting increasingly expensive as people move from rural to urban areas, where they can make more money in less time. There are many reasons for this. Greatly affecting the efficiency of vegetable crops. Both weed problems and inadequate care Therefore, in this research, a real-time soil, solar, and weather monitoring system was created for farmers to enable them to know the actual conditions of their crops and to calculate the correct watering and fertilization. It saves time in agriculture.
From the research, the researcher has set up a program to monitor humidity, temperature, and pH. Then, put the equipment and the screen into the steel box so that it is easy to set up at the vegetable plot. Once the system is set up correctly, farmers can use their own cell phones to look at information about their vegetable plots. The experimental results found that using equipment to monitor the environment of the vegetable plots helped farmers spend less time caring for the plots. Also, the productivity of the vegetable plots that have been set up with this kind of system is good. The researchers tested it with farmers who grew kale. The cultivated kale yielded good yields similar to those of normal kale but took less time. We compared kale growth between kale grown in greenhouses and kale grown outdoors. The results showed that the overall increase in the first period was not different, and the later period of kale grown at the farm showed better growth.
