# 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&#x20;
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)"&#x20;

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.
