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 ...

While a mosquito bite is often no more than a temporary bother, in many parts of the world it can be scary. One mosquito species, Aedes aegypti, spreads the viruses that cause over 100,000,000 cases ...

Infrared sensors that detect the short-wave infrared (SWIR) region can clearly recognize objects not only during the day and at night, but also in fog or smoke, making them a key component of future ...

Infrared radiation is given off by heat, either body heat on the ground or jet engines in the air—making IR-seeking ...

The Xiaomi Human Body Sensor has been announced in China via a crowdfunding campaign. The new Xiaomi Human Body Sensor is the latest gadget to be integrated into the Xiaomi smart home ecosystem. The ...

Infrared sensors used in thermal imaging cameras and for body temperature detection have been difficult to produce without toxic materials like mercury. A South Korean research team has developed the ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

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 ...

A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next-generation optical sensor technology capable of precisely detecting not ...
