"基于单片机的太阳能热水器控制系统设计与实现"

With the continuous growth of the global population and economy, the environmental problems caused by energy use are gradually being recognized, and the concept of "low-carbon economy" has begun to enter people's field of vision. Solar energy has the "infinite" reserves and universality, and it hardly produces any pollution. In view of this, people are vigorously developing the solar energy industry. Solar water heaters meet the requirements of the times and satisfy people's demand for environmentally friendly and green products. In today's increasingly advanced civilization, it is the best choice for modern civilized society. This article proposes a new design scheme for a solar water heater control system. The design uses the MSC-51 series single-chip microcontroller AT89S52 as the central processor, and uses modules such as DS1302 real-time clock and 12864 dot matrix LCD screen to complete functions such as displaying time, temperature, and water level, and setting time and temperature.
