IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it into electrical signals. There are two main types of sensors: ...

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, ...

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 ...

Michigan Technological University’s Michigan Tech Transportation Institute (MTTI) and Michigan Tech Research Institute (MTRI), in cooperation with the Center for Automotive Research and the Michigan ...

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, ...
