DFRobot Capacitive Liquid Level Sensor for Arduino is used to detect high-viscosity and low-corrosive liquids. These liquids include glue, lubricating oil, grease, ink, engine oil, powder, and other special materials. The sensitivity of the sensor can be adjusted by the knob (clockwise to increase, counterclockwise to decrease) to adapt to more media. It has an indicator light to feedback the sensor status in real-time and comes with polarity protection and over-current protection mechanism.
