Single-Trigger Liquid Level Module

1.  Non-contact liquid level detection.

2.  Single-level detection.

3.  Digital I/O output.

4.  LED status indication.

5.  Applicable to containers or mounting surfaces with a flat surface only.

● Description :

1. This module enables through-wall, non-contact water level detection in non-metallic containers, such as internal water tanks in coffee machines or water dispensers, and can replace traditional float-type level sensors.

2. During operation, when the water level rises above the sensing position, a corresponding TTL logic output change is generated. (If the water level remains below the sensing point or unchanged for 10–15 seconds, the output signal will automatically reset; therefore, this condition is not considered part of the detection state).

3.  When the water level is higher than or equal to the sensing area, the output is HIGH, and the LED indicator is ON.

4.  When the water level is below the sensing area, the output is LOW, and the LED indicator is OFF.

● Applications:

1. Single-trigger applications, such as beverage filling production lines; not suitable for continuous level monitoring.

2. Liquid level detection for coffee machines, water dispensers, and plant pots.

3. Other applications requiring liquid level detection through a container wall.

4. Metal or electrically conductive containers are not allowed.
