Design of Intelligent Washing Machine Based on Single Chip Microcomputer
Abstract
With the improvement of quality of life and the popularization of smart home concepts, the demand for intelligent and personalized washing machines is becoming increasingly prominent. Traditional washing machines have problems such as single functionality, extensive control of water level and duration, lack of precise sensing and adaptive adjustment capabilities, and are difficult to meet the cleaning needs of different types of clothing and stain levels. Therefore, it is necessary to develop a washing machine with environmental perception, mode adaptation, and intelligent interaction functions.
This design proposes an intelligent washing machine system based on STM32F103C8T6 microcontroller. The core functions of the system include: real-time monitoring of water temperature through DS18B20 temperature detection module, combined with relay to achieve heating control; Using the HX711 pressure sensor to detect the weight of clothing and provide a basis for adjusting water volume; Utilizing Molsture water level sensors to accurately sense water levels and ensure water volume adaptation; Through independent buttons and SU-03T voice module, cleaning mode switching and voice control are achieved, supporting five modes: large object cleaning, soaking cleaning, intelligent cleaning, bucket self-cleaning, and high-temperature boiling cleaning; OLED display screen displays real-time water temperature, water level, clothing weight, and current working mode; Simulate water discharge valve control through SG90 servo motor, MX1508 drives DC motor to simulate washing rotation, and dual relays control heating and blowing functions respectively; Trigger sound and light alarm reminder after laundry is completed.
The function of this intelligent washing machine is to achieve precision and personalization of the washing process through multi-sensor fusion perception and intelligent control logic. It can automatically adapt cleaning parameters based on clothing weight and water level, and meet different scene needs through diversified modes. At the same time, it improves operational convenience through voice interaction and status display, providing users with an efficient, energy-saving, and intelligent laundry experience, and helping to improve the quality of smart home life.
