VCC 5V Power input
GND GND Ground
AOUT A0 Analog data output

Examples

  • Please download and install Arduino IDE to your PC.
  • Download the demo codes, unzip and find the Arduino examples
  • Open the Liquid_Level_Sensor.ino file by the Arduino IDE
  • Build and upload the codes to the UNO board
  • After uploading, you can open the Serial Monitor of IDE and check the data

Expected result

When the module is inserted into water, the serial port outputs data. The higher the water level, the greater the data.
