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

①Totally out

Output Voltage: 0V
Output Current:0mA

②Immerse part of the module

Output Voltage: 3.22V
Output Current:28mA

③Immerse full part of the module

Output Voltage: 3.42V
Output Current:32mA

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

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.

When the immersion depth of the module reaches the setting value, the LED on P13 of arduino board is bright.
