Virtual Sensors in Digital Twins

"By definition, a virtual sensor is a type of software that, given the available information, processes what a physical sensor otherwise would. It learns to interpret the relationships between the different variables, and observes readings from the different instruments. Think of it as a kind of a “ghost” of the physical sensor." (Chad Jackson)

“The idea here is that if you’re running a simulation and you’re getting accurate inputs, and it is mimicking the behavior of a product in real life, in real time, you can then instrument that simulation model with taking measurements at different locations. You are going to be getting readings from that virtual sensor, which is where you’re taking measurements, and then you can actually use that to complement physical sensors.
