This study is aimed to develop a multi-functional monitoring system based on remote spectral imaging and environmental sensing for seedling production in the greenhouse. The crop images during cultivation received and stored in the database of the computer. After analyzing the data in the database, the main control computer got the condition of crops in greenhouse and took some correct procedures such as fertilization and irrigation to control the environment in greenhouse by comparison the developed standard database of crop cultivation. The field test showed the possibility and potentiality to shift the cultivation methods of vegetable production by manual operation in greenhouse to remote control and management system and saved manpower and raised the quality of vegetables.
