[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sensors ...

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 ...

Recently, the progress of uncooled infrared (IR) sensors has been remarkable due to microelectronic systems (MEMS)-based pixel structure, in which free standing thermal isolation structures are ...

Infrared sensors that detect the short-wave infrared (SWIR) region can clearly recognize objects not only during the day and ...

An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

From self-driving cars to facial recognition, infrared sensors are all around us and our novel semiconductor research is taking this technology to the next level. Phlux - a Sheffield spinout -has ...
