Today’s smartphones are incredible little machines—able to perform the function of ten gadgets within a single compact device. From professional-grade cameras and GPS navigation to automatic display ...

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 ...

How transimpedance amplifiers are used in fiber-optic communications, laser rangefinders, and LiDAR systems. How avalanche photodiodes enhance TIA performance. Application-specific design and topology ...

One of the most interesting parts of the Nintendo Switch has gone nearly unused by game developers, including Nintendo, for the first year of the system’s existence. A mind-blowing demonstration ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

Well suited for engineers and R&D teams tackling complex industrial challenges, especially in agri-photonics, plastic sorting, and spectroscopy for food safety, these new InGaAs area image sensors ...

Lumenara says that other features include a fast rolling shutter, 8- or 10-bit digital output, and input–output control for synchronization with strobe and peripheral devices. Both come with a C-mount ...

Cameras that see both visible light and infrared could enhance the next generation of 3D and virtual reality cameras, as well as expand the capabilities of driverless cars that rely on camera systems.

Tempe, Arizona - Southwest Microwave, a leading global supplier of perimeter intrusion detection systems, has announced the introduction of the advanced Model 420 Passive Infrared (PIR) Sensor for ...

The sensor allows non-contact monitoring of moving objects with temperatures from 250 to 1250 ºC (482 to 2282 ºF) or in inaccessible or harsh environments. Units are available with 4-20 mA interface ...

A sensor identifies misfolded protein biomarkers in the blood. This offers a chance to detect Alzheimer's disease before any symptoms occur. Researchers intend to bring it to market maturity. The ...
