The examples provided are based on the Arduino UNO, if you need to use other Arduino boards, please check if the board is compatible with the UNO.
Hardware connection
Liquid | Arduino | Description |
---|---|---|
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.
