# DLI Virtual Sensor

Day Light integral virtual sensor is available for configuration only in case when an workspace has at least one sensor with **PPFD** or **PPFD\_μmol/m²s** metric. The DLI virtual sensor creates one measurement per 24 hours at a specified time. Output value shall be calculated only in cases when at least 90% of input values are available. This will represent the amount of Photosynthetically Active Radiation (PAR) received each day as a function of light intensity and duration. DLI in Aranet Cloud is calculated according to the formula:

This option can be selected only by having a PAR sensor, and it will be located as the last option when clicking on "New Virtual Sensor". To create a virtual DLI sensor, navigate to the **SENSORS** menu -> **VIRTUAL SENSORS** tab and press the **NEW VIRTUAL SENSOR** button:
