STMicroelectronics is launching a human-presence and -motion detector to enhance security systems, home-automation equipment, and IoT devices that typically use passive infrared (PIR) sensing. The ...

It is critically important for instrument users to understand what the sensors in their instrument cannot properly measure, as well as what they can. Non-dispersive infrared (NDIR) sensors are ...

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 ...

If you've ever been on your sofa and wondered how long you might have to queue for a bike at the gym or how long the wait is for a table at your favorite restaurant, then the Density sensor could ...

Mid IR Sensors is defined as type of sensor designed to detect and measure electromagnetic radiation in the mid infrared range of wavelengths. The devices installed with Mid IR sensors are capable of ...

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 ...

The University of Hawaii (UH) has released the first image obtained using its new 16-megapixel HAWAII 4RG-15 (H4RG-15) image sensor on the UH 2.2-meter telescope on Mauna Kea. This represents a ...

Thermal infrared (IR) energy is emitted from all things that have a temperature greater than absolute zero. Human eyes, primarily sensitive to shorter wavelength visible light, are unable to detect or ...

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 ...
