Gravity: Non-contact Digital Water / Liquid Level Sensor For Arduino

If you have any questions on this product please feel free to contact us.

*Disclaimer: The images are merely illustrative

This is a non-contact water / liquid level sensor for Arduino. It utilizes advanced signal processing technology by using a powerful chip (XKC-Y25-T12V) 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 this liquid 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. Four levels of sensitivity can be configured by pressing the SET button.
