CQRobot Non-Contact Water/Liquid Level Sensor for 3-10 mm Diameter Pipelines Compatible with Arduino, Raspberry Pi and Other Boards. for Industrial, Aquarium, Chemical Solution, Agriculture, etc.
 
Product 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
         
Designed for non-metallic pipes with an outer diameter of 3-10mm (maximum 11mm). The spring leaf can open and close no more than 60 degrees and is compatible with plastic/glass/ceramic containers (wall thickness no more than 20mm)
