Abstract

In farms, forestry centres and greenhouses, the system can be used in growing seedlings of crops , breeding of plant and vegetables in cold areas. It may control all the activities automatically in temperature, humidity , sprinkling and heating. This is a closed-cycle control system controlled automatically by single-chip microcomputer. (MCS-51) The purpose of this system is to shorten the experimental cycle of crops , improve the survival rate of crops breeding, and ensure the growth of vegetables in the cold areas. Therefore, it can be used widely.
