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 ...

Eliminating the need for a separate magnetic lid sensor, the CM36262 integrates a patent-pending optical lid sensor with an ambient-light sensor (ALS) and proximity sensor, thus simplifying the design ...

Researchers have developed a highly sensitive method for detecting hotspots in the environment, such as bushfires or military threats, by harnessing the focusing power of meta-optical systems. The key ...

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 ...

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 ...

Researchers developed a type of infrared photodiode that is 35% more responsive at 1.55 m, the key wavelength for telecommunications, compared to other germanium-based components. Detecting infrared ...

Researchers have fabricated a new high-performance shortwave infrared (SWIR) image sensor based on non-toxic colloidal quantum dots. They report on a new method for synthesizing functional ...
