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 ...

Shortwave infrared light (SWIR) sensors are desirable in a broad range of applications, particularly in the service robotics, automotive, and consumer electronics sectors. Colloidal quantum dots tuned ...

The sensing solution detects flammable hydrocarbon gases in oil and gas refineries, manufacturing plants and mining environments.

As the U.S. Army produces third-generation forward-looking infrared (FLIR) sensors, officials are exploring emerging capabilities that might be integrated into fourth-generation systems. FLIR ...

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 ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...
