Capacitiv (V)

1. Connecting the Sensor:

   • Connect the capacitive sensor to one of the input channels (1-4) and the GND (ground) pin on the VAN PI OS.

   • Use pin 5 or 10 to supply the required 12V/24V power to the sensor.

     • These Pins on the VAN PI CORE provide the input voltage (12V/24V) n

     • These pins are fused by a PTC fuse to protect against overcurrent.

2. Configuring the Sensor:

   • Access the system's web interface.

   • Navigate to the settings for the input channels. Config -> Sensors

   • Set the desired channel pair to "Capacitive" (you can only set channels pairwise: 1&2 or 3&4).

   • You can also change the Sensor names

3. Measuring Voltage:

   • The system measures the voltage output of the capacitive sensor. For sensors like the Votronic sensor, set the sensor to output a maximum voltage of 2.4V when the water tank is full by adjusting the potentiometer on the sensor.

4. Calibrating the Sensor:

   • Full/Empty Calibration:

     • Fill the water tank to its maximum level and set this as the "Full" value in the web interface.

     • Empty the water tank completely and set this as the "Empty" value.

   • Direct Votronic value Setup:

     • You can setup directly to 2.4V full sensor value by clicking "SET SENSOT #x VOTRONIC (MAX 2.4V)"

By following these steps, you can effectively integrate, configure, and calibrate both resistance and capacitive sensors with the VAN PI OS, ensuring precise water level monitoring for your application.
