coffee industry and in the home, ensuring that the accurate monitoring of the water level is crucial to the quality of the brewing coffee and the normal operation of the machine. In this environment, traditional contact sensors may face the problem of water quality change, scale or pollution, while non-contact liquid level sensors can provide a more stable, accurate and reliable liquid level monitoring scheme. Challenge: Coffee machines need accurate level monitoring to ensure enough water to brew high-quality coffee. Traditional contact sensors may be affected by water quality changes, scale, or contamination, resulting in inaccurate liquid level monitoring or requiring frequent cleaning. The operation process of the coffee machine requires an efficient and stable liquid level monitoring system. Results: Coffee quality improvement: The non-contact liquid level sensor ensures the high liquid level monitoring and accurate supply of water in the coffee machine, and helps to ensure that the quality of the brewed coffee is consistent. Intelligent operation experience: The intelligent liquid level control system provides accurate liquid level monitoring through non-contact sensors, and automatically stops or starts the water pump, so that the coffee machine can intelligently maintain a stable water level in different situations, and improves the users operation experience. Cleaning and maintenance cost reduction: non-connectTouch sensors reduce the frequency of cleaning and maintenance, reduce the maintenance cost of coffee machines, and improve the overall benefits of the equipment. Energy saving and environmental protection: the intelligent control system accurately controls the start and stop of the water pump through non-contact sensors, realizing energy saving and environmental protection, in line with the sustainable development of modern life
