With the development of The Times, everyones life pace is getting faster and faster. Many office workers are under great work pressure and often drink coffee to refresh themselves. Most of it is made in a coffee machine, which is more efficient, but if you dont stare at the coffee machine, there will always be a lack of dry water, water overflow, and the risk of electric shock. In order to better solve the safety risks caused by the lack of water and dry burning in the coffee machine, it can be prevented by installing a non-contact liquid level sensor to detect the low water level automatic control heating device. Furthermore, non-contact level sensors can detect relatively high water levels to prevent overflow.
Therefore, when the non-contact liquid level sensor does not detect the water, the warning light will be on (or alarm), which is the function of the sensor to realize the water shortage protection of the coffee machine. When the level sensor does not detect water, the sensor will signal to make the device start to add water. When the water is added to a certain position, the level will signal and stop adding water to completely overflow.
