Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

Properly choosing an inductive proximity sensor can be challenging. Learn about the critical factors to consider when making your decision. Inductive proximity sensors detect the position/presence of ...

Today, most modern Android devices are kitted out with a bunch of sensors. You can use this information in lots of different ways – whether it’s monitoring light levels so your application can ...

STMicroelectronics' engineer Tom Bocchino explains how the company's TMOS sensor can detect human presence and proximity. STMicroelectronics' TMOS sensors handle presence sensing using a 5- to 20-µm ...

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 ...
