Development of water culture planting kit with the energy – saving

Abstract

This research is the development of an energy - saving water planting kit. The objective is to develop a prototype of an energy - saving water planting kit by applying solar energy as an energy source that is controlled by the Arduino board through a blynk application and study the efficiency of the water culture planting kit. By comparing electricity usage rates between solar energy and electric power from the household. In this study, there were 4 experimental sets. The experiment was water cultivation without installation, 2 experimental sets and 2 experimental sets were installed using green salad vegetables. In research, the 45 days growth period consisted of leaf length and width, root length, number of leaves and height. There is also a comparison of the efficiency of AB fertilizer and soy milk hormones to reduce chemical usage. The research has shown that the use of the soybean milk hormone provided a high growth rate of Lactuce sativaVar. Longifolla than AB fertilizer. There are many nutrients, but only in small amounts. When used as a nutrient for plant growth needs to be changed daily. Considering the economic value, using AB fertilizer as a nutrient will be worth more than soy milk hormones. For the installation of the instruction set and the LED lamp was suitable for Lactuce sativaVar. Longifolla growing than not installing the instruction set and the LED lamp. These can save electricity cost of 85 baht per month.
