How to Configure VAUX Using the Zenseio Mobile App
5.3 VAUX Settings (LSMP or CSMP devices only)
If the device is equipped with auxiliary voltage generator inputs, VAUX pin provides output voltage to power or bias an external sensor.
Generated Output Voltage - sets the power supply voltage for the connected SDI-12 probe or other types of external sensors. The voltage depends on the requirements of the used sensor. In general, the lower the voltage, the lower the battery consumption. For example, 8V works well for most popular soil moisture probes, but this voltage may need to be increased for long cable runs if the probe reading is not working correctly. The available choices are 5V, 8V, 9V, and 12V. Please consult with the probe/sensor specification to see what is the lowest voltage that can be applied.
