Virtual Sensors

Virtual Sensors allow you to generate new, calculated measurement values based on data from existing physical sensors in your workspace. This feature enables deeper analysis, comparisons, or combined insights without requiring additional hardware.

In the Virtual Sensors tab, you can view all configured virtual sensors, check measurement history, edit their settings, and create new ones. Each virtual sensor uses input data from one or more sensors and performs calculations automatically at every incoming measurement interval.

Virtual sensors can be used to:

• Combine or compare different sensor readings
• Normalize or correct input data
• Calculate environmental indicators such as dew point or vapor-pressure deficit
• Create advanced mathematical expressions for custom monitoring needs

When creating a new virtual sensor, multiple predefined calculation types are available, including:

• Offset – apply a manual adjustment to a measurement value
• Sum – combine values from several sensors
• Average – calculate average measurement from multiple sources
• Ratio – compare two sensor readings
• Expert – manually configure formulas, slope, and normalization
• Vapor-Pressure Deficit – calculate atmospheric dryness using temperature and humidity
• Day Light Integral - calculate the amount of photosynthetically active radiation
• Dew Point – estimate the condensation temperature from humidity and temperature data

Virtual Sensors help enhance your monitoring setup by transforming sensor data into more meaningful metrics—fully automatically and in real-time.

Virtual sensors that are configured using more than 1 sensor (including Sum sensor) will only calculate if all source sensors are available & have sent in measurements for the particular time slot. In case 1 or more sensors have lost connection to the base station, then the virtual sensor will not calculate any measurements for that period.

Once all sensors become available again, the virtual sensor will resume calculating measurements starting from the first time slot that has received all source sensor measurements.
