This is a water level sensor which can detect the presence of water and the water level. The reading is high when the water level is high.

### Precautions

* If the sensor is not in use for a long time, please store in a dry container to prevent oxidation due to moisture.
* A warning line is printed on the module, do not insert the sensor deeper than this line as this may cause damage to the circuitry.

### Connecting the module

Connect the Environment Module to Armourbit with a 4Pin cable first, then connect the sensor to the module with a 3Pin cable.
