Infrared emitters and receivers have multiple applications for smart home appliances, for example the cleaning robot sensors used for path planning of coverage region and the switch sensors for hand-dryers. Through infrared sensing, household appliances can become smarter and make our lives simpler.
To enable gamers to press keys faster, gaming keyboards uses IR/PT optical switches.
Optical switch keyboards have short actuation time and long lives, a recent trend for keyboards.
Optical imaging can be achieved through utlilizing pairs of IR/PT location sensors.
Optical touchscreens can be hung on top of screens that have corresponding sizes to generate the effect of touchscreens.
The functions and performance of mobile devices continue to improve. Infrared sensing products are widely used in applications such as proximity sensing and infrared/laser focusing of camera lenses to bring precision and efficient capabilities to mobile devices.
Busy working, people often neglect their health. Wearable health-control devices use light sources of different wavelengths with bio-sensing IC to monitor daily health status and alert people to pay attention or boost certain aspects of health.
The security systems often save energy through using infrared light as additional lighting. Light-sensing IC are used to control the usage of infrared light.
