Gravity: Non-contact Digital Liquid Level Sensor for Arduino

This is a non-contact water / liquid level sensor for Arduino. It utilizes advanced signal processing technology 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.
