AB - Aiming at the problems of water temperature and water level control system of  conventional solar water heater and low solar thermal control efficiency,  this paper developed an AT series single-chip solar water heater control  system for rural areas. In this paper, the detailed design of hardware and  software is presented, and the method of evaluating the collector efficiency  is simplified by the temperature rise rate and solar irradiance of the  collector plate. The software compensation algorithm we adopted can  effectively reduce the impact of different water quality on water level  measurement and improve solar thermal control efficiency. It is found that  the control system designed in this paper has the characteristics of low  cost, high safety, and strong practicability.
