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 ...

Thermal infrared (IR) energy is emitted from all things that have a temperature greater than absolute zero. Human eyes, primarily sensitive to shorter wavelength visible light, are unable to detect or ...

To guarantee measurements from infrared (IR) photonic sensors with certain accuracy, radiometric calibration (RC) is implemented to determine the radiometric responsivity of sensor and usually be ...

Most consumer remote controls operate using infrared light. This works well assuming the piece of equipment has a line of sight to the remote. But if you have, say a receiver in a cabinet or closet, ...

While smartphones are awesome little computers, one of the things that really makes them useful is their built-in sensors - many apps are made possible via a phone's accelerometer, gyroscope, GPS, ...
