The Design of Solor Energy Heater Controller Based on MCU
Abstract：To economize and utilizee nergy resource,especially the lasting energy resource, is a problem that humankind has faced.The Solor Energy Heater is becoming more and more popular for its characteristic of low price and low energy consumption.But the controller is studying and developing.To solve the problem of control the temperature and the level of water automatic, with water temperature sensor for sensin technology,automatic control system for Solar Water Heater based on MCU is designed. This control system through the pressed key establishment control mode, may realize all-weather provides the hot water uninterruptedly, and has prevents the spatial fever with the height water temperature water level warning function.
This article mainly introduced the monolithic integrated circuit solar-powered water heater observes and controls meter's contents and so on hardware, software's design and debug method.
Keywords: Solar energy heater; MCU; Controller;Automatic control system
