      Welcome to Sensirion Labs

      Sensirion stands for innovation. To inspire engineers and developers who are working with our sensor solutions, we have founded a new section called «Sensirion Labs». There you can find documentation to various ideas, which our employees came up with - for example how to use a differential pressure sensor to measure adblue / urea concentrations in liquids or how to build a pulse monitor.

Antifogging in VR Goggles

The trend of virtual reality (VR) goggles is steadily growing. More and more people are buying virtual reality devices to experience this new way of perception. With this new technology shortly launched broadly, we are experiencing some problems like fogging inside of virtual reality goggles for example. To increase the user experience as well as the comfort, Sensirion has a solution for avoiding fogging inside goggles. By implementing Sensirion’s SHTW2 humidity sensor it is possible to avoid fogging caused by perspiration. This “antifogging” feature is not only applicable with VR goggles but can be also applied to other goggles like skiing goggles or motorbike helmets.


Antifogging in VR Goggles - Implementation

Working Principle

  • Measurement of RH @ T of surface
  • Prediction -> active prevention
  • Principle widely applied in automotive

Implementation Concept

  • Prediction and detection of fogging in VR goggle is possible
  • Prevention with heating or venting

Related Information

  • Use Case "On/Off-Body Detection"
