Function Introduction

 

Functional Test

Testing environment:barreled pure water
Testing procedures:
1.Connect the module to 5V power supply
2.Put the module to into the pure water
3.Observe the relation 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
According to the three groups of data, we can make a conclusion that the actual testing results meet the requirement of application.
