Temperature/oxygen concentration-based aeration control system was designed and realized to control the process of aerobic composting. The outline, method, function and process of realization of the system were described in detail. By 2 week aerobic composting with this system, it showed that the system could run stably during composting and the composting temperature, humidity, and oxygen concentration can be monitored by the system. The time of temperature remained at 55～65℃ was more than 9 days. The pathogenic microorganism can be killed and the stability of product is good. 
