The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

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 ...

TransDigm Group has agreed to acquire Simmonds Precision Products from defense contractor RTX for approximately $765 million in cash. TransDigm said the transaction is subject to U.S. regulatory ...

ifm presents new inductive proximity sensors in full metal housings in three sizes for safety applications: M12, M18 and M30 with a housing length of 60 mm. For use in mobile machinery, they are ...

This article details six essential sensors, along with four necessary questions a design engineer should ask before choosing which ones to use in their next design. In the R&D and electronics design ...

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 ...
