Gravity: Non-contact Digital Liquid Level Sensor

SKU: SEN0204

The Gravity non-contact liquid level sensor uses advanced signal processing (powerful high-speed chip) for non-contact detection. Suitable for hazardous applications (toxic, strong acid/alkali, high-pressure airtight containers), it has no special liquid/container requirements, is easy to use/install, compatible with DFRobot Gravity via adapter, and has 4 sensitivity levels set via the SET button.
