Functional Introduction:

Functional Test

• Testing environment:barreled pure water
• Testing procedures:
• Connect the module to 5V power supply
• Put the module to into the pure water
• Observe the connection depth between the immersion depth and the output voltage of AO end.

Actual testing results

Actual application case

Use this water level sensor module to control on or off about the LED which is on the arduino board

Tools:

• arduino uno
• Pin Header
• Dupont Cable

When the immersion depth of the module does not reach the setting value,LED on P13 of arduino board is not bright.
