- Abstract
- Damages due to abnormal weather are frequent throughout the world, and long - term drought can ruin farming, and heavy rainfall can cause damage to crops and subsequent damage to pests and diseases. In order to solve this food shortage problem, various plant factories utilizing information technology (IT) are growing steadily in USA, Japan and Europe. Domestic plant factories have not yet reached commercialization stage, but they are continuously researching and developing. The government is taking steps to secure the basic technology of plant factories that combine agriculture with IT technology in order to supply food and solve farmers' difficulties. In this thesis, lettuce grown at a relatively early growth stage was classified as A, B, C, D. In this case, A and B stages are composed of a spray system, C and D stages are composed of a fresh water system, and the growth rates of plants according to a nutrient solution injection method are compared. By applying the effect of light wavelength of LEDCLigh仕ng Emitting Diode) on plants, optimal growth environment of light wavelength is derived. For this purpose, PLC (Programmable Logic Controller) automatic control system using IOT(Internet of Things) sensors has been constructed by combining Arduino, PLC, touch screen and smartphone system and designed the system suitable for container plant by comparing growth rate of plants.
