Aquariums and aquarium fish has bee a family favorite, a fashion, more and more families at large would in everyday life people do not have more time to care for pet fish, water and climatecontrolled, while the Aquarium is also on the market of heating and water installations but is independent and is expensive. Designed circuit is simple, small, intelligent very realistic aquarium system. This article has designed an aquarium based on singlechip microputer intelligent systems, temperature control modules, water level modules, SCM module and liquid crystal display module. STC89C52 SCM as the core control of the system, the measured temperature and water level fed into the STC89C52 MCU for parison, by parison to determine whether drive heating and water pumps, and in 1602 LCD display temperature on water level.
