Capacitive Liquid Level Sensor for Arduino

Description Capacitive Liquid Level Sensor for Arduino Offers NPN + PNP dual output Detects high viscosity and low corrosive liquids Conical head of anti-hanging-liquid design Detection Mode: Contact detection Power Supply Voltage: 12 - 24 V The Capacitive Liquid Level Sensor for Arduino is used to detect high-viscosity and low-corrosive liquids, such as 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 on the sensor status in real-time and comes with polarity protection and over-current protection mechanism. Capacitance contact detection: Determine whether there is liquid and distinguish between liquids by detecting the capacitance of the liquid. Conical head of anti-hanging-liquid design: Reduces the phenomenon of hanging liquid in detecting. Special circuit
