# Simulation

Simulate data from the selected device to test visualizations, dashboards, or data processing workflows without needing a physical device.

For Adding A Virtual Value source, select the Value on the option selection.

Name is a descriptive name for your Virtual Value device

Than select physical copy of you want to generate or you can create your own simulation data object.

Data Frequency: Define how often the virtual sensor should generate data.

Configure sensor range configuration: Based on your device selection from catalog set ranges for sensors that can be used in simulations. You can select a randomize range or type a custom range for a given sensor.
