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 ...

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 ...

If your garage door is having trouble opening or closing, it could be due to a sensor issues. Luckily, you can easily fix ...

A new way to make large ultrathin infrared sensors that don’t need cryogenic cooling could radically change night vision for the military or even autonomous vehicles. In a study published today in ...

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 ...

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 ...
