Highly Sensitive Water Level Sensor for Arduino


Product details:

  • Sensor type: water level sensor
  • No of pins: 3
  • Colour: Red
  • Dimension: 65mm x 20mm x 8mm
  • Weight: 3g
  • Package contains:1 x water level sensor


Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface. It is a continuous level sensor that measures the level within a specified range and determines the exact amount of substance in a certain place. It is a low cost, accurate, simple, small, portable, low power consumption, high performance, water sensor. It gives better output with Arduino having 328 microcontrollers. The output is obtained by having a series of parallel wires exposed traces measured droplets/water volume to determine the water level.
