A STUDY ON MICROCOMPUTER CONTROL METHOD OF HYDROPONIC GREENHOUSE ENVIRONMENT

A useful microcomputer control method of hydroponic greenhouse environment has been developed based on the present situation and the needs of scientific research, and embodied in a basic microcomputer control system with apple Ⅱ, which controls air temperature, humidity, light, CO_2 as well as the temperature and circulating supply of nutrient solution.The results of comparative simulation showed that the methods is feasible.
