Introduction
The non-contact liquid level sensor utilizes advanced signal processing technology by using a
powerful chip with high-speed operation capacity to achieve non-contact liquid level detection.
No contact with liquid makes the module suitable for hazardous applications such as detecting
toxic substances, strong acid, strong alkali and all kinds of liquid in an airtight container under
high pressure. There are no special requirements for the liquid or container and the sensor is easy
to use and easy to install.
The liquid level sensor is equipped with an interface adapter that makes it compatible with
DFRobot "Gravity" interface. There are 4 levels of sensitivity which are set by pressing the SET
button.

Results
If the liquid level sensor detects the liquid level, it will output HIGH and turn the LED ON. If no
liquid is detected it output LOW and turn the LED off.
