Proximity sensors, which are designed to detect the presence of nearby objects without any physical contact, have evolved from narrow application in industrial automation systems into broad use. They ...

Touch-free user interfaces are the new trend for automotive design engineers. There are multiple ways to implement this feature, and one of them is through proximity sensing. Proximity sensing is a ...

STMicroelectronics' TMOS sensors handle presence sensing using a 5- to 20-µm passive IR sensor. This provides more accurate results as well as information about the distance rather than just a basic ...

Time-of-flight (ToF) sensors open up new application areas and use cases for proximity sensing and presence detection technologies, and these sensors can add valuable functionalities and intelligence ...

What's behind the target can make a tremendous difference in how well reflective sensors do their job. Consider a photoelectric sensor operating in simple diffused mode (i.e., as a proximity sensor).
