ABSTRACT
Household water dispenser as a necessity, its intelligent control is increasingly important. Traditional water dispensers have shortcomings in temperature and water management. Rough temperature control, affecting drinking experience and health; Water management is not accurate, which can easily lead to dry burning or water interruption, affecting service life and family safety.
Based on STM32F103C8T6 single chip microcomputer intelligent control system for home drinking water dispenser, through the integration of a variety of sensors and intelligent control algorithms, to achieve the accurate management of water temperature, water volume and user operation. The system uses the waterproof DS18B20 temperature sensor to monitor the water temperature in real time to ensure that the water quality meets the temperature range set by the user; At the same time, the built-in weighing module accurately detects the amount of water, avoids the occurrence of dry burning, and alerts the user in time when there is a shortage of water through a buzzer. In addition, the system can also set the upper and lower limits of temperature, switch the power supply and control the water pump through the key operation, providing users with a convenient operation experience. In terms of information display, the OLED screen clearly displays the current water temperature and water volume, which is convenient for users to grasp the status of the water dispenser at any time. It is worth mentioning that the system is interconnected with the mobile phone through the Bluetooth module, and users can remotely obtain water temperature and water information, and can set the upper and lower limits of water temperature and switch the power supply through the mobile phone APP, which greatly improves the intelligent level of the drinking machine.
In summary, based on STM32F103C8T6 single chip microcomputer intelligent control system for home drinking water machine with its excellent performance and convenient operation mode, will lead the intelligent trend of home drinking water machine industry, for the majority of families to bring more healthy and comfortable drinking water experience.
