Hardware preparation
Software preparation
Wiring preparation
Arduino UNO+Arduino expansion board. Use the 4PIN wire to connect the sensor to the A2 port on the Arduino expansion board.
Note: If you do not use the Arduino expansion board, please use DuPont cable to connect the sensor to the Arduino development board
Note: If you do not use the Arduino expansion board, please use DuPont cable to connect the sensor to the Arduino development board
Arduino programming code
- Connect the Arduino UNO development board with the expansion board to the computer through the USB cable
- Use Arduino IDE to open the program
- Select the corresponding development board and open the connection port
- Open the serial port monitor and set the baud rate to 9600, upload the program
- Insert the sensor into the soil with different humidity and observe the data changes
