Design of Solar Energy Water Heater Control System
Abstract: Aiming at the drawbacks of current domestic solar water heaters such as complicated operation and inconvenient control characteristics, this topic designs a automatic control system of the water level and water temperature of the solar water heater of measurement and control. It is with the single chip processor as the core, the temperature detection circuit used by DS18B20 digital temperature sensor, and by placing electrodes contact sensor measuring water level in the tank, using the LCD1602 and leds to show the water temperature and water level, through the electric auxiliary heating and solenoid valve to realize the function of automatic heating and automatic water electromagnetic. This system has realized the intelligent control of the solar energy water heater.
