CQRobot Capacitive Non-Contact Liquid Level Sensor for Arduino Raspberry Pi

Key features

• Adopting the principle of capacitive sensing, the liquid level signal is accurately triggered by the change of liquid capacitance, with high detection accuracy
• Non-contact liquid level sensor with indicator light, adjustable sensitivity, compatible with Arduino/Raspberry Pi, provides relevant test code, and real-time detection feedback
• Double DIP switch design: the right side switches the signal voltage (3.3V/5V), and the left side reverses the detection output logic (high and low levels are adjustable), which can flexibly adapt to various control needs and is stable and reliable
• It has high sensitivity and anti-interference ability, non-contact liquid detection, corrosion resistance, can detect boiling water, no mechanical loss, and long life
• Applicable to the outer wall of non-metallic containers (outer diameter D of the pipe is not less than 11mm), compatible with plastic/glass/ceramic containers (wall thickness no more than 20mm), and used for liquid level detection of various curved, arc-shaped, cylindrical containers or pipes
