Household appliances and commercial appliances such as humidifiers, water dispensers and dishwashers need to detect the lack of liquid detection by using liquid level switches. For example, multi-point photoelectric sensors can be used to achieve a level detection of high and low liquid level, and a sensor can reach low liquid levels. Remind you to add water, stop adding water at high liquid level. The D2LS-B launched by EPT is a multi-point photoelectric level sensor. One sensor can detect four liquid levels. It has 3 wires and is very convenient to connect.
