From your smartphone’s face recognition feature to fancy fitness trackers and advanced night vision cameras, many sensors we use daily rely on infrared light detection. For the last eight years, a ...

Inspired by the infrared sensory organs of snakes, which allow them to detect prey in complete darkness, researchers at UNIST ...

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 ...

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 ...

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 ...

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.
