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 ...

We all know that feeling: you've turned the lights off and are almost asleep when you hear that infamous buzz. A mosquito is hunting in your bedroom. The dance commences. You could turn on the lights, ...

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 ...

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 ...

RTX feels that advanced electro-optical/infrared (EO/IR) sensors are coming of age for detecting unmanned air vehicles, missiles, and aircraft at extreme ranges. US defence giant RTX feels that ...

Infrared sensors, which act as the "seeing" component in devices such as LiDAR for autonomous vehicles, 3D face recognition systems in smartphones, and wearable health care devices, are regarded as ...

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 ...
