To connect the soil moisture sensor and water level sensor to your Arduino board, you will need to follow the instructions provided in the manual. Here is a step-by-step guide:
1. Gather the necessary hardware: Arduino microcontroller (such as Velleman WPB100 Arduino Uno), soil moisture sensor module, and water level sensor.
2. Connect the +5V supply line (VCC) of the module to the 5V line of the Arduino board.
3. Connect the GND (0V) of the module to the common ground connection of the Arduino board.
4. Connect the analogue signal output (usually marked as S on the module) to the analogue input A0 of the Arduino board.
5. For the soil moisture sensor, insert the sensor head into the wet soil. The moisture will bridge the probes through a low-resistance path, resulting in a change in the output voltage.
6. For the water level sensor, make sure the sensor parts are covered with water. The analogue value will be available at the "SIG" connection.
By following these steps and using the provided code example, you should be able to connect and use both the soil moisture sensor and water level sensor with your Arduino board.
